Enjoy! The cardboard should be about six feet high and three feet wide. Unlike other chris, my eyes glazed over. Muzzle velocity changes to an estimated amount of fps. As the bullet travels down the barrel, propellant gases build pressure and accelerate the forward motion of the projectile. Hell understand when you tell him how productive it will make you. Comments like this are why people dont like this community. Because we dont know it is 2400 yet, we enter 2500 first. *yikes* hope no one paid money for this advice. Josh- Two things puzzle me. Select a scope to prefill the following data attributes or enter your own values. 2023 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. It carries no practical penalty for me because I mainly bring it out when I will be hunting from a fixed location. Is it actual MOA, like 1.06 at 100 yards or is it 1? Ill tell you one thing . 5. Youtube, ABOUT US Note: my opinions on shooting arent entirelypopular with the shooting community. Velocity doesnt matter at all. As a rule the faster the muzzle velocity the shorter the bullets time in flight and there for a flatter trajectory and less drop. Instagram In fact, the faster an object is moving, the more kinetic energy it has. For a game animal or a human attacker to die, there must be sufficient blood loss, usually through significant damage to the vascular system or a major blood-bearing organ. For much of that time Ive been missing targetsat long distances. Since youre shooting with mils, make note of the impact. But I can sorta verify bcs by measuring at the muzzle and downrange (Superchrono downrange) and calculating from those values. Use the calculator below to calculate the kinetic energy of a bullet. 2400? There will be a day when even a FFP mil/mil is obsolete, but were not there yet. Even the factory loads that produce the best accuracy from this rifle are very inconsistent in their velocity and this really surprised me! Thats not nothing. That time, you hadeverything justright. JavaScript is disabled. It allows you to estimate velocity based on your current zero and the amount of drop at another chosen range, say 300 yards. . 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. Lyman found that barrel and load would give about 1573 fps muzzle velocity. Sight height isnt that critical, unless you eat nails for breakfast and mount your ACOG on your carry handle. If I was having a rifle built it would wear a 22 barrel, and experience shows I would still be carrying a nearly 300fps advantage over a 13.5 barrel. Typical handguns have muzzle velocities in the range of 1,000 ft/s, which means that such a bullet would travel a mile in a little over five seconds if it hit nothing or did not fall to the ground by that point. Youll discover that you will certainly want a temp-stable powder like Varget. Because we don't know it is 2400 yet, we enter 2500 first. For years now Ive been a long distance shooter. Now that you know thats 3 mils, hold those 3 above the target and off to the side. While this seems logical when you look at the numbers, the reality is very different. This is the number placed into the ballistic computer as your muzzle velocity. grains. The Accura LR boasts a 300-yard shooting capability by providing better velocity through its 30" Nitride-treated Bergara barrel. Also look at H-110. 2. So the differences for the 21/2 difference in barrel length were 136 fps, 144 fps and 153 fps . Yes you can. Remember, it isnt about speed or barrel length. Copyright 2023/ Privacy Policy / Terms & Conditions. If you know the acceleration of the bullet, you can determine muzzle velocity from the kinematics equation. We have better things now and these advanced optics and rifles will become the overwhelming standard in the next few years. If you can stretch your memory back to high school science, you should remember that kinetic energy is the energy of motion. Is there a calculator out there somewhere on the interseine for estimating black powder velocities? Remember, Targets4Free.com is your number one online source for 100% free targets, as well as resources like this one! Assume 100 yard zero. function gtag(){dataLayer.push(arguments);} The value of the stability calculator is more in comparing different combinations with each other (twist rate, bullet to be used, muzzle velocity, environmental conditions, etc.) Find the velocity, feet per second, of the exiting pellet. That load produces 2400fps from a 13.5 barrel. just because it's impractical for hunting or target shooting is not a valid reason to dismiss the need for sufficient velocity. 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). Do not touch that elevation dial. . Firearm Setup. Well, one thing you can do is use our bullet comparator tool to see what the differences in ballistic performance is likely to be if you switch bullets. Yes actually and Ill elaborate on how to figure that out in a minute . Good for you, bruh, because its party time. Nope nope. Theres a reason that computer guided optics are becoming a thing these days. Tell your boss youre sick of your garbage gun show accessories and that you need a raise to get that US Optics glass. Set max as your actual max, so 500m for me.

Big deal right? 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. It is paramount to calculate the correct muzzle velocity and to use the appropriate ammunition for the firearm, in order to maximize the accuracy . Best barrel length for 5.56mm (and .223 Remington) depends on your use case. Best Overall Barrel Length for 5.56 NATO. Although there are other factors that affect terminal ballistics such as the bullet shape and type, the kinetic energy of a bullet is useful for comparing different cartridges. The sensor relies on measurement of magnetic field induced voltages which are unique as the ammunition leaves the muzzle . 3. I find I get my best prone and offhand done at that distance. I've found many "tables" to range from poor to worthless. Eagle) | 124gr | 1120 fps | 345 |, 9mm (Hornady Crit. The only thing that matters is your philosophy of use and how you apply it to your gear. Ive done similar work before with the JBM site.

Spoiler alert: Rosebud is the sledand that book looks better on your coffee table, where it begs to be mentioned by college friends who knew you were in the military but didnt know you werent a sniper. I guess I am going to be the guy that gets bunched up on your velocity/caliber claim. The modifications permit estimates for less than nominal full loads and . Yeah, this method is sort of a way to reverse-engineer your velocity. Do that at any range you have and then print off your data. Use your imagination. You already know that you have 3 mils to the dot. 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. I hear you F-Class guys and this isnt for you! Dude calm down aint nobodys advocating killing american LE and MIL when there is not a revolution going on. For a step-by-step guide on how to use the program, CLICK HERE! Anyways, go to jbmballistics.com and begin punching numbers. Check shot one. ; Add both the resultants and divide them with the mass of the firearm in grams to get velocity of the firearm. Since Im struggling as it is to keep this whole yards and meters thing straight, Im just going to go full metric. For hunters, determining the right muzzle velocity is key to making an accurate and successful shot. In the case of a gun, the bullet replaces the piston in the cylinder . The calculated \(v_{new}\) should turn out to be 2,669. BUT, if you triple the velocity you get 9 times the energy due to the V being squared in the energy formula! I never hunt with regular hunting bullets. Whether you need help solving quadratic equations, inspiration for the upcoming science fair or the latest update on a major storm, Sciencing is here to help. None of that cant garbage needs to be worried about in real life. Ignore wind speed for this time. There you have it. This calculator will display the foot pounds of energy, and help you compare the power of different loads. I love the long range stuff too . Copyright Ammotogo.com 2023 All Rights Reserved. Muzzle Velocity (fps) Ballistic Coefficient. Sure enough, you have holes at 2.1 mils. The ballistic performances for the 7mm-08 Remington based off a 24 inch test barrel on two grain types for muzzle velocity are 2,800 ft/s (140 gr Nosler P), 2,650 ft/s (150 gr Speer HC-SP). Understanding and studying the kinetic energy of a bullet is important in determining terminal ballistic performance. To convert from ft/s to m/s, divide by 3.28. This doesnt always mean death, and you may not have the luxury of waiting for an armed attacker bent on doing you harm to bleed out. Ive tested a variety of chronos and they are seldom fully accurate. HANDGUN BALLISTICS. Believe it or not, these are two very different things. Ad & Review Requests This muzzle energy calculator should prove pretty useful in a wide variety of applications. (Thats 10cm at 1000m for those of you that measure in Freedom Units only.) For my abilities and shooting the El-Cheap-o rifle I am, I think its excellent. Josh Wayner is a Michigan native, active competitor, Grand Valley State University alumni, troublemaker, and fiction author. Triple the mass triples the energy. Youve just proven your immaturity to every sane person reading this. 7. The heavier the bullet and the faster it moves, the higher its muzzle energy. than trying to say simply if a bullet is stable or unstable. Its about building a range card based on data. Math is irrefutable and forces you to accept facts. Free Ballistic Calculator. Firing under anything other than Standard Metro conditions changes the effective ballistic coefficient of the projectile (from Sierras 6th Ed). Getting ones load standard deviation down into single digits of fps is challenging, but it can be done. Since my long range shooting primarily revolves around hunting, velocity also matters quite a bit where your bullet has a specific velocity threshold where it will expand and disrupt tissue as opposed to turning into a copper and lead ice pick, and your deer runs off to be eaten alive by coyotes. When you have it zeroed, find the longest distance you can possibly fire at. No, not really. Lets face it: youll never be so operator that your drop chart matches the one in Guerrilla Sniper. Removing margin of error is preferable to claiming superiority based on simplicity. Enter the first two variables, then press calculate. 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. One frequently hears the expression describing an . Enter a BC and matching drag function, or select a bullet from the library and then enter the following variables: Muzzle Velocity. Data entry. Muzzle energy is the energy of a bullet right when it leaves the firearms barrel. You will learn more than I have time to write on this page. 4350 is good powder. It will change, so leave it on one setting for this procedure. Its all relative, people. Next Post . It isn't difficult to calculate the average pressure required to push a bullet out the muzzle of a gun at a certain velocity. In the next set of inputs, dont really mess with most of that. This article led me to looking into temperature sensitivity of powders. I like the method for establishing drops as well, I dont always have access to a chronograph and this will likely be a valuable tool for me in the future. Causing immediate death with any firearm is difficult and there certainly needs to be an amount of luck on the shooters side, especially with the adrenaline and chaos that go with a dynamic situation. 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. Energy: FPE. Because P = F/A, F = ma, and the area A of the cross-section of a cylinder (which a gun muzzle can be assumed to be) is r2 (r being the radius of the muzzle), a can be expressed in terms of these other quantities: Alternatively you could get a rough estimate of the bullet's velocity by measuring the distance from the muzzle to a target and dividing this by the time it takes the bullet to reach the target, though there will be some loss due to air resistance. My best friend wears a badge and I used to wear chevrons. Modified Point Mass Trajectory Calculates a trajectory from bullet dimensions. Something about lots of spectators makes my finger jump . Muzzle Velocity: Actual muzzle velocity corrected to the muzzle from the chronograph location. 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. Impractical range begins at 1000. What youll need is ; Velocity doesnt matter in the long run because its only a small factor in overall accuracy. You may not have mils, but you do have a Sharpie. It's based on the assumption that a rifle will impart the same amount of kinetic energy to both bullets. Save that information. If youre really careful, you can actually take that permanent marker and draw mils on your glass. Consistency builds confidence and confidence builds consistency. A comfortable solid platform . $$v_{new} = \sqrt{m_{known}v_{known}^2 \over m_{new}}$$. by dellet Fri Oct 21, 2016 9:25 pm. Change barometric pressure or temperature and all that work is for naught. All of these calculators find the muzzle velocity at the shooting temperature by using linear interpolation given two muzzle velocities and two temperatures. I have been fortunate, for the two main loads I shoot in this rifle I have found good accuracy nodes on the higher end of velocities, but without having to run at max charges or push pressures. As gun people, we often become obsessed with ballistic data, particularly with energy and velocity. (Grains) Velocity. Register today and take advantage of membership benefits. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity.

I may try switching to H4350 where I was using H414. Tell me thats not important. Skip down and change the units to mil in the first column and to centimeters @100m in the second one. The muzzle velocity of the bullet. Every fanboy seems to want to throw in humidity and Coriolis like theyre trying to impress someone, but it matters so little in real life at realistic ranges that its just safe to set it at 50 percent all the time. If your memory is a little off you may take a pencil and a notebook but leave your calculator at home . But, it shouldnt just be tossed aside. The calculator allows a range interval as small as . If an object is moving, it has kinetic energy. The 175 grain Eagle Eye loads I use do 2,620 out of my 20 LTR. But precision is not equal to accuracy. Pressure and temperature is different when the max ord is dozens of yards above sight line and this is assuming you are not shooting across a valley. However, its nice to have solid data when youre scrolling through a website trying to choose the best ammunition option; Its hard to argue with numbers, after all. Or more. Yes, but you're going to need to get your wallet out. Heres where it gets interesting. b) how consistent is your muzzle velocity? Our Friends Using holdover I was able to figure out to aim 11 inches high with a Ruger semi auto .44 mag @ 200 yards, talk about slow velocity, fire gun, 1 wecond silence and then whap. Use the calculator below to calculate the kinetic energy of a bullet. The standard deviation (aka "SD") is a measurement that shows how much variation from the average number exists in a sample. Humidity can be simply set at 50 percent. I actually dont like shooting past 500m these days. Fact is, my method works and offers the flexibility that modern people need when shooting for score or in the field. Go buy Magpuls Art of the Precision Rifle. Were at 5.6, so too slow. Bullet Properties. But do get that marker and a measuring tape or meter stick. lb Muzzle Velocity ft/sec. Thanks for the article. Although we dont always like it, a hunter can shoot an animal and let it run off a short distance to expire. . Doesnt this mean your method of attaining MV may yeild a wrong value for MV? No apologies, and youre welcome. I supposed someone could put the numbers in Excel and the program would "calculate" the #'s for you basically by just doing the math. 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. Mils are stoopid. After you make those shots, drive down and put markers or draw visible indicators over your bullet holes, which are certainly (or should be) directly under your target center. A decent high power rifle with a quality barrel , I enjoy my Noreen BN 36 for 500 yarders . You can calculate kinetic energy using the classic formula you memorized in Physics class.

I push 2815 fps with a similar load to the one you mentioned out of my 26 308 (disclaimer on that in a second). 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. Semi-auto, (eg .308/7.62 for M1A)? Bullet or shot weight (gr) 1 oz = 437.5 gr. That happens to be the longest distance at my local range. 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. 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. What should come first:consistency. Neither does energy. Bullet Energy Calculator. After its initial release onto the commercial market the 7mm-08 Remington gained popularity amongst shooters for the rifles quick handling, accurate . Ahh, the science of walking it in and then running calculations backward. Tarkov Ballistics Calculator. However, for this to occur, the barrel would have to be impractically long. Go to the next section and enter atmospherics. Fpe - The bullet energy in foot-pounds at that distance. You'll need only three added pieces of information [3] for your situation: Bullet weight, New charge weight, New Barrel Length. Just to be a problem, Ill do 2300fps. The Train and the Defend ammunition produces the exact same muzzle energy and velocity. Keep it consistent and youre golden. Chronologically, this takes placei. Muzzle energy is a prime comparative figure and could be the reason you pick one load over another. 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. Here goes: velocity isnt important. Get out that barely-relevant copy of The Ultimate Sniper and hope that it holds the answers. For the record, the bullet is the 150 grain Federal Fusion.
