muzzle velocity calculator

Just curious how well youre .308 setup does at 800, 1000, 1200, etc. Hell understand when you tell him how productive it will make you. Put a night force on pops 94 youll plug hogs n yotes from a mile away just use that handy dandy ballistics calculator ignore the wind, it doesnt matter! 380 Auto +P: JHP: 90: 276: 1175: 380 Auto : Xtreme HPP: 70: 233: 1225: International Cartridge Corporation Ammunition Ballistics: Round Type Weight Muzzle . Believe it or not, these are two very different things. I know probably during your career youve only run into the type that would trade their lives for mine, but that by no means indicate the totality of the situation. Muzzle energy is often used to rate the lethality of certain loads. Muzzle Energy is useful in comparing cartridges, calculating recoil, and stopping power. In words, the bullet energy KE (in foot-pounds) is equal to the bullet weight (in grains) wb times the square of the bullet velocity v (in feet per minute) divided by 450,437. No wait. yards. You're not currently signed in. . Something about lots of spectators makes my finger jump . Most of you have missed more shots than youve made, except that one time you lucked out and actually hit that pop can that somebody else left on the target rail on the 300 yard line of your local range. What Barriers Do To Ammunition Testing Data, The Best Self Defense Ammo Ballistic Testing. Muzzle Velocity: Actual muzzle velocity corrected to the muzzle from the chronograph location. Unless youre in a competition like that, the 6XC and like calibers dont hold up against things like the .308 for real use on game. Bison Ballistics Munitions, LLC Generally speaking, the longer the barrel, the greater the muzzle velocity (and thus the greater the muzzle energy) because there is more length for pressure to build before the air creates drag. That last number is a constant created by multiplying two times the acceleration of gravity by 7,000 - the number of grains in a pound. Kneel before Zod. Select your ammunition to prefill the following data attributes or enter your own values. The problem is very similar to taking a compression check on an automobile engine to see if the piston rings and valves are sealing the cylinder well. (Grains) Velocity. Although death may still come in the end, it isnt the actual goal. Also, Microsoft Paint. Our free Ballistic Calculator generates thousands of shot simulations using your provided load, muzzle velocity, and real-world environmental conditions to create the most accurate bullet drop compensation data available. Those unknowns will make the outcome of the program into just a guess. Its all broken down into tens. You should carefully consider weight retention and projectile expansion or fragmentation as well. Not sure how well he did but hes got some amazing skills. Mainly, you ignore bc. wisdom vs. experience or, today I learned What Muzzleloading Stuff Did You Do Today. Pure math, man. Or more. e ( CD / BC / 8816) x CV = MV. Inconsistent muzzle velocity results in vertical stringing. Foot pounds is a standard unit of energy used as part of the English Engineering Units, a set of measurements commonly used in the United States. This number can be used to get a rough idea of a round's destructive potential. We thought you might enjoy it as well. To calculate the muzzle velocity, a velocity measurement, the ballistic coefficient and the distance from the muzzle to the measurement point are required. Best barrel length for 5.56mm (and .223 Remington) depends on your use case. Josh Wayner is a Michigan native, active competitor, Grand Valley State University alumni, troublemaker, and fiction author. Bullet Energy . One frequently hears the expression describing an . 1000 is an imaginary landmark 46 @1000 is nothing and easily accounted for. Max Range. I HATE MATH !!!!!!! With the muzzle velocity calculation function, the bullet velocity V measured at a distance of x meters/yards can be converted to the bullet velocity V at the muzzle of the barrel (at 0 m/yds). Considering that a bullet from a Marine M40A5 is only seven grains heavier and a paltry 100fps faster coming out of a 24 barrel, Id say were doing just fine with the shorter barrel. 300 Blackout, not just for sub-sonics. No amount of calculation is completely accurate. Enter a BC and matching drag function, or select a bullet from the library and then enter the following variables: Muzzle Velocity. Stop it. Id like to add a couple of things to what Josh said here: Mostly true. Let MV = The Muzzle Velocity calculated from the Chronograph Velocity. That said, Ill elaborate on how to maximize your accuracy with a standard duplex reticle but it wont be easy. Have you ever wanted to compare a fast lightweight bullet to a slower heavy bullet to see which one hits harder? Chances are good that youve had to follow a blood trail before recovering game. Our goal is to make science relevant and fun for everyone. You make note of it, hold with the start of the duplex, so 3 mils, on the target center and fire a few more times. No apologies, and youre welcome. If you arent shooting with a true first focal plane mil/mil scope right now, youre seriously handicapping yourself both at the range and in the field. In a gun tube for firing rounds of smart ammunition, a sensor means applied to the ammunition which enables the calculation of muzzle velocity in the instant as the ammunition leaves the muzzle edge of the gun tube. Count the number of mils to the wide part of your duplex and make note of it. If thats a fast load, then good for you. inches. Thanks for the disadvice but the point of the question is as stated, whether or not someone had created a program yet for plugging in ball diameter, powder charge, barrel length and any other data points. See the Resources for an online tool that allows for the input of very granular information about specific firearms and bullets to achieve estimates of muzzle velocity and other data related to ballistics. I shoot way too many different rifles and loads, so having a good bc and mv, when I can get them, might be quicker than even your method. I really love what my stubby barrels are doing for me. All these fancy things are there to make that first shot and every shot better. Or momentum. Now, if I drop muzzle velocity to 2400fps that brings minimum expansion range all the way in to ~325 yds. Okay, so technically your gun now has two known zero points. This article led me to looking into temperature sensitivity of powders. This muzzle energy calculator should prove pretty useful in a wide variety of applications. If the barrel is too long, the friction of the bullet against the interior wall of the barrel will overcome the pressure of the expanding gases, slowing the bullet rather than accelerating it. lb Muzzle Velocity ft/sec. I would call this a reference more than a calculator. ; Find the product of mass and velocity of the powder charge. Skip down to the third column inputs. Assume 100 yard zero. Because we don't know it is 2400 yet, we enter 2500 first. They perform the tests in a controlled laboratory environment. Watch for splash and impacts. ProChromo, CEDM2, Magnetospeed, Superchrono (measures from sonic boom), and Labradar. Facebook Using my pet load with a 165gr Nosler ballistic tip (min expansion @ ~1800fps) over 45grains of Varget (thats a full grain below max charge) pushed to 2815fps puts my maximum expansion threshold at 550yds or so. How fast a bullet is traveling when it leaves the end of a gun's barrel, called the muzzle velocity, is of great interest to both those who work in the field of ballistics and physics students looking to cover a few key concepts in one, well, shot. What Im about to say will bunch a lot of shorts in a lot of places. Arguing ballistics in regard to killing our own people is disgusting and irreverent tobthose who died in the line of duty. It is also the energy that the shooter absorbs through recoil by shooting. Designed to expand, hollow points slow as they move through soft tissue, dumping energy into the target rather than passing straight through. Sighting (yards) Range Card. The standard deviation (aka "SD") is a measurement that shows how much variation from the average number exists in a sample. Since the AR-15 rifle is such a highly customizable gun, there are various features you can change which impact muzzle velocity, and we'll examine them below. Units of Measure . Its about building a range card based on data. This number can be used to get a rough idea of a rounds destructive potential. It can find the time of flight, but also the components of velocity, the range of the projectile, and the maximum height of flight. Its the same projectile, but the speed it travels greatly affects the energy it carries at impact. $$v_{new} = \sqrt{m_{known}v_{known}^2 \over m_{new}}$$. To calculate muzzle energy, or Foot-Pounds Equivalent (FPE), you need to know the mass of the item being moved and the velocity it will be . Chronographs can be had for around $100 and they definitely have their place. Instagram BC = 0.300. So for existing firearms, longer barrels equal higher muzzle velocity and therefore increased muzzle energy. It is by no means a calculator, as it uses averages and gives ballpark figures. Ralston, NE 68127 The firearm generates a muzzle energy of approximately 130 ft lbs of energy at the muzzle whereas that of the air rifle is only about 26 ft lbs. In order to determine the kinetic energy, you must know the velocity of the bullet and the weight of the bullet in grains. 1. Its reactive and gives instant feedback. 5. Range (yards) Range Velocity Damage Penetration Power Drop Time of Flight; 0 y: 0.00 fps: Yes. 3. I have mine memorized at 300 , 500 and 800 yards and can do a 10 inch gong in 3 shots almost every time . Go to the next section and enter atmospherics. where v 0 = initial velocity = 0, x = distance traveled inside the gun barrel, and v = muzzle velocity. That load produces 2400fps from a 13.5 barrel. You cant avoid it. It is ironic in a way that ammunition manufacturers stamp muzzle velocity and muzzle energy on their product packaging. Muzzle Energy will be rounded to the nearest whole number. We had three high velocity loads that measured close to 1300 feet per second - The 40-grain copper plated round nose version of the CCI Mini-Mag , the 40 . Dont do that. It meters nice and burns clean. Chronologically, this takes placei. Definitions. Our calculator creates a proper ballistics trajectory chart that details range, drop, velocity, energy (fps), wind drift, and time. The real variable in long range shooting is wind, nothing helps you negate its effects better than a high BC bullet with good speed. Anyway, thanks for writing this, I would like to see more posts on long range shooting. Muzzle velocity changes to an estimated amount of fps. please call 1 (833) 784-5520 for assistance. To use the calculator, simply fill in the input values (blank white boxes) in the large black box. Theres a lot going on with ammunition. It's a quick and dirty sanity check if you're thinking about trying a new bullet and want to know about how much velocity you will gain or lose. Fire. All of these will lead to inaccuracy in the ballistics solution and the best way to compensate right off the bat is more velocity. Muzzle energy is the amount of energy a bullet carries right out of the barrel. Click calculate, this will show you under Results 2 the aproximate Muzzle Velocity in FPS and Meters Per Second and Range in Feet and Meters for your Airsoft Gun. Something totally and boringly predictable. Calculating Muzzle Velocity and Trajectory With Five Shots (Or So). I actually dont like shooting past 500m these days. Your 308 load moves approx 46 more at 1000 yards than my .260 load in a 10 mph wind. Thanks for the article. Different brands and batches of blackpowder will vary and that can't be put into the program because it won't be known. Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. Enter the actual temperature of the day. By the way to prolong the service life of you brain by preventing overheating just buy MagnetoSpeed. CD = 7 feet. Standard Metro conditions are: To calculate the free recoil energy of a firearm, the weight of the gun, the weight of the powder charge, the weight of the bullet or shot+wad and the muzzle velocity are required. Just enter your bullet weight below and its velocity. Its far more complicated than high school math, even if that sometimes feels like the most complicated thing on planet Earth. Its about how uniform all your gear is. Fact is, my method works and offers the flexibility that modern people need when shooting for score or in the field. Im a 30.06 guy , always will be , I collected way to much brass . Big secret: humidityhas no valid bearing on real shooting. So I am not only confused and perplexed by this, but am wondering just what it is Ive been attempting to understand all these years. By continuing to browse our website you agree to our use of cookies. Well Josh , Ill try to save you a lot of trouble here and it wont take a lot of charts and fancy $2,000.00 scopes and any math . What We Use | 115gr | 1140 fps | 332 |, Thanks again for using our free muzzle energy calculator tool. You should always pick the load that gives you the best results. How to use the Range Calculator. Our Friends Even the factory loads that produce the best accuracy from this rifle are very inconsistent in their velocity and this really surprised me! Breath deep , exhale , and walk em in and write em down . Shown in the table below are a few sample calculations of both Projectile Velocity and Barrel Pressure for the 9mm, .357 magnum, .44 magnum, .45 ACP, .223 / 5.56 NATO, .308 / 7.62 NATO, and .50 caliber BMG using CFR's derived method. It drops a bit at 1K+, but if you use your data, the hits come as regularly as with any caliber. If you are a hunter, youve probably shot an animal that didnt drop in its tracks. A well-placed shot with less than stellar ammo is more effective on animals, whether fur bearing or criminal, than a poorly placed shot with the best performing ammunition on the market. Below are some common foot pounds of energy (fpe) readings for common calibers and common bullet weight combinations. Your point A is 100m, but your 500m point B isnt your expected 5.1. Then. Muzzle Energy will be rounded to the nearest whole number. No amount of calculation is completely accurate. The Federal Ballistics Calculator lets you quickly determine the trajectory for any rifle or handgun load, and save data for an unlimited number of loads. It doesn't have any major disadvantages in velocity and is still overall quite maneuverable. . COPYRIGHT 2021, THETRUTHABOUTGUNS.COM. You get the drill. I never crimp bolt gun ammo. Eagle) | 124gr | 1120 fps | 345 |, 9mm (Hornady Crit. Check shot one. Interval: Output solution distance i.e. By default, we only need four values to give you a good idea of how your shot will behave: target range, bullet weight, muzzle velocity, and ballistic . Drift - The horizontal drift from a cross wind. Modified Point Mass Trajectory Calculates a trajectory from bullet dimensions. The muzzle velocity algorithm uses the known barrel length, the time the projectile 410 travels down the barrel (event E), and the calculated ammunition powder burn rate to calculate a value for the projectile muzzle velocity. I have found variations in my crony similar to yours using both hand loaded and factory. What should come first:consistency. Use this ballistic calculator in order to calculate the flight path of a bullet given the shooting parameters that meet your conditions. Velocity is heavily determined by the length of the AR-15's barrel. Thats how velocity affects muzzle energy. The guys at PRB are good, but they get real stale with their presentation and ideas on philosophy of use. Too fast. Help me identify this beautiful flintlock rifle, please. Shooters in self-defense situations dont have this luxury. Now you know you have a bullet that impacts 5.1 mils low at 500m. Once a baseline is established, you can alter it at will to match your conditions. And Im trying to figure out how/whether the ballistics you generate are correct regardless (wrong MV, wrong bc, correct drops), which must be true since it works. window.dataLayer = window.dataLayer || []; Buy Strelok. 5865 S 77th Street . Were at 5.6, so too slow. Youll discover that you will certainly want a temp-stable powder like Varget. The Impact Ballistic program allows to you to match your specific cartridge to any of the TRACT riflescope reticles, providing BDC (Bullet Drop Compensation) for long range accuracy and precision in a simple and easy-to-use online program. Abstract. Getting ones load standard deviation down into single digits of fps is challenging, but it can be done. I know people like you and you wouldnt last a minute against those you call goons. Vox: The State of Gun Violence in the U.S. Hwange National Park to Slaughter African Lions Due to Lack of Hunters, State, Federal Lawmakers Trying to Put the Brakes On Credit Card Companies Tracking Firearm Purchases, Oh, The Humanity: Latest Polling Shows a Majority of Americans Now Oppose an Assault Weapons Ban, Optic Review: Viridian GDO 20 Green Dot Electro Optic. the figures were 1,187 fps and 1,331 fps. . Best Overall Barrel Length for 5.56 NATO. This is why soldiers and police officers are trained to aim for center mass, it increases hit probability even though an instant kill is highly unlikely. gtag('js', new Date());

For me, they are at 5.1 mils low of a 100m zero at 500m. Ooooook, Yeah, but you get much more use out of high quality glass than a chronograph that will wind up shot, sooner rather than later. Thanks. Ah, 2400. One thing Ill unhappily confirm: chronos are a pain and not reliable. You can hover over the question mark icon on any field to learn more about how that field will impact your calculation. Once the bullet exits the barrel, the gases dissipate, pressure drops, and air resistance begins to slow the bullet. The 150-grain bullet has a muzzle velocity of 2,820, while the 180-grain has a muzzle velocity of 2,620 feet per second. The energy in Winchester Train rounds is sufficient to take down a threat in most defensive situations, the problem is where the energy goes. EDUCATION 101. (Heres that disclaimer I promised) I will be the first to admit that a 26 barrel is pointless on a 308, but thats how my rifle came from the factory, and to the extent I have hand loaded for it so far it shoots lights out so I am inclined to leave it be. + 1 inch at 50 yards, 0 at 100 yards, -5.2 at 150 yards, and -15.3 at 200 yards. Muzzle Velocity Calculator Ballistics Calculators Diameter (in) Weight (gr) Ballistic Coefficient (G1) Sectional density = 0.226. What about it? They are by no means a traditional hunting bullets (the 185 is a tactical OTM whatever that means) but even Berger lists a suggested minimum velocity though, beyond that you are primarily relying on the bullet yawing to disrupt tissue which is proven time over to not be a consistent or reliable thing. Its easy to understand why we get so deep into the numbers. x and y are horizontal and vertical displacement in meters (m), t is time in seconds (s), a is acceleration in m/s2, and g = the acceleration due to gravity on Earth, 9.81 m/s2. Thats good to know, I havent hunted with the hornady hpbt bullets ever, but I am working on loads for a 168gr and 185gr Berger bullet which are holding promise. Can we really live without pissing off everyone else at the range while we set up a chronograph and force them all to hold fire so we can stand in front of the line? HANDGUN BALLISTICS. Def.) If you'd like to learn more about each of the specific environmental factors, check out our list of frequently asked questions. I forgot to mention that I also have shot .300 BLK out to long ranges and found the hits to be easy to make. So, real world performance can vary greatly. Once you've completed the form click the calculate button to generate your ballistic compensation drop chart. Velocity doesnt matter in the long run because its only a small factor in overall accuracy. What would YOU DO if an Airsoft Ref came up to you like this? So spend some time on the range and become proficient with your weapon of choice. Muzzle energy is the energy of a bullet right when it leaves the firearms barrel.
