Worry not, friend, I wont come out empty-handed. gtag('js', new Date());

This is the major problem with using FMJs for anything other than target shooting and recreational plinking. I dont doubt you Josh , it just doesnt appeal to me and Ive been a reloader for 25 years . Theres a reason that computer guided optics are becoming a thing these days. . For much of that time Ive been missing targetsat long distances. This is a useful measurement in that you can use it to compare power settings of an airgun, the energy . The latter is the way to go, but even there I get funny results maybe errors on my part in recording exactly what load Im shooting, but it happens a lot. It is paramount to calculate the correct muzzle velocity and to use the appropriate ammunition for the firearm, in order to maximize the accuracy . Im sad that people like you are part of the community. You'll need to Sign In or create a Ballistix Account if you'd like save your calculation data. A comfortable solid platform . Ive always thought velocity had to be consistent to have decent accuracy, but my empirical evidence says this is not true. An old black powder gunsmith in NC gave this to me 30 years ago: And after everything is done based on using information gathered in Zonie's post and you have gone to one of the Black powder loading manuals that has tables of velocity information for similar rifles, you. In a nutshell, a heavy bullet traveling at a slower speed is going to . Here it is for those of us who have long since forgotten: To translate for the less mathematically inclined, kinetic energy equals one-half the mass of an object times the square of its velocity.. Those were the CCI 40-grain Polymer Coated Clean-22 and the Eley 38-grain Subsonic Hollow Point . 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. a gun image by timur1970 from Fotolia.com. I like their stuff because I get it, but I have a hard time agreeing with some of their ideas. There you have it. Im joining this conversation a bit late so dont really expect any kind of reply, but heres my situation. I have never seen one, probably too many variables. There is no sight height, no bullet weight, and no muzzle velocity because Marc doped gravity, not a set of specific conditions. Amer. Since Im struggling as it is to keep this whole yards and meters thing straight, Im just going to go full metric. It takes into effect things like atmospheric conditions, wind, and even allows you to make projections shooting both up and down hill. So, real world performance can vary greatly. If you buy a Lyman reloading manual, youll see that they call out an accuracy load as well as a maximum load in their tables. What would you consider the max hunting / target range of your platform? 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. Theres a lot going on with ammunition. For me, they are at 5.1 mils low of a 100m zero at 500m. that would mean in almost 2 decades of hunting I would have passed on exactly one shot, but that extra 225 yards of effective range means I am not pushing the equipment right up to the edge of its limits when taking shots at any reasonable range I hunt at. Lets face it: youll never be so operator that your drop chart matches the one in Guerrilla Sniper. Assume 100 yard zero. The muzzle velocity of the CCI Stinger Ammo is 1,640 fps compared to the . + .7 inches at 50 yards, 0 at 100 yards, -4 inches at 150, and -12.1 at 200. The Accura LR boasts a 300-yard shooting capability by providing better velocity through its 30" Nitride-treated Bergara barrel. Great read, where in West Michigan is there a 500 meter range? Or momentum. If thats only 300 yards, thats fine, but it wont be as precise as longer distances. Dont bother with the other inputs in that section. Impractical range begins at 1000. Ive shot in competition, hunted successfully out to 500m+ and have never worried about it. Kestrel 5700 Ballistics Weather Meter with Hornady 4DOF. Unlike other chris, my eyes glazed over. As gun people, we often become obsessed with ballistic data, particularly with energy and velocity. I have found variations in my crony similar to yours using both hand loaded and factory. Max Range: The furthest distance you want to be represented in your trajectory output. We also collect information about your rifle scope so we can provide you with compensation results specific to your scope's make and model. CD = 7 feet. 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. Tell your boss youre sick of your garbage gun show accessories and that you need a raise to get that US Optics glass. We use cookies to improve your browsing experience. 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. This article led me to looking into temperature sensitivity of powders. In just a few seconds, an attacker can carve you up like a Christmas ham and leave you bleeding in the street. Distance to Chronograph needs to be 0.0 since we arent using one. Skip down and change the units to mil in the first column and to centimeters @100m in the second one. 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. 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. 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. b) how consistent is your muzzle velocity? While deep penetration is great for reaching vital organs, too much penetration can cause the bullet to pass completely through the target, taking that energy with it. RIFLE BALLISTICS. Velocity doesnt matter at all. Diameter. There are many other variables that can affect the bullet . One thing Ill unhappily confirm: chronos are a pain and not reliable. A shooting chronograph is a tool that measures the speed at which your bullets leave the barrel of your gun. Fact is, my method works and offers the flexibility that modern people need when shooting for score or in the field. Do not touch that elevation dial. I dont trust chronographs but I do trust math. No, not really. Free Ballistic Calculator. Move your reticle over to your target and hold the nearest round mil onto the dot in the middle of your target. . Buy Strelok. If you enjoy the articles, downloads, and calculators on the Bison Ballistics website, you can help support it by using the links below when you shop for shooting gear. It will a produce a line graph showing the bullet drop and flight path of the bullet. Please share, like, and tweet this page and others to show your support. I wasnt sitting with you when you took your shots so I will take your word for it though. Examine the problem to find the displacement of the object and its initial velocity. Count the number of mils to the wide part of your duplex and make note of it. A page devoted entirely to traditionally styled .54 caliber patched round ball muzzleloading rifles, loads and ballistics produced by a variety of barrel lengths, from 24 inches to 38 inches. Bullet Energy . The more complicated answer: Muzzle energy is the measure of kinetic energy a projectile carries when it . where v0 = initial velocity = 0, x = distance traveled inside the gun barrel, and v = muzzle velocity. Wad weight (gr) BC. Bullet or shot weight (gr) 1 oz = 437.5 gr. Quick! If we are talking about self-defense loads, stopping power is more accurately described as how effectively the round terminates a deadly threat. What? Dont under estimate the importance of #7 . BC and MV are just inputs for generating trajectory (drops), and youre working from actual drop, so . By using these equations, you can determine the path of a fired bullet and even correct for drop due to gravity when aiming at a distant target. a) do your rounds go trans-sonic on the way to the target? JavaScript is disabled. The energy in Winchester Train rounds is sufficient to take down a threat in most defensive situations, the problem is where the energy goes. Formerly with ScienceBlogs.com and the editor of "Run Strong," he has written for Runner's World, Men's Fitness, Competitor, and a variety of other publications. Ralston, NE 68127 Long range on the target line starts at 600m. When you start talking about 200-400fps though, yes, velocity absolutely matters. On the other hand, Winchester Defend rounds are topped with jacketed hollow points. The sensor relies on measurement of magnetic field induced voltages which are unique as the ammunition leaves the muzzle . Different brands and batches of blackpowder will vary and that can't be put into the program because it won't be known. Mainly, you ignore bc. All projectile-motion problems are free-fall problems, because after an initial velocity is given to the projectile at time t = 0 of the problem, the only force acting on the projectile is gravity. Excellent write-up. Units of Measure . Velocity - The velocity in fps at that distance. I've found many "tables" to range from poor to worthless. Confirm your data using shorter shots. The kinetic energy of the bullet is the energy that is transferred to the target when hit. Neither does energy. -Muzzle Velocity (fps) 11 10 9 1/2 9 8 1/2 8 7 1/2 7 6 5 4 3 2 1 BB #4 Buck #3 Buck #1 Buck #0 Buck #00 Buck #000 Buck -Shot Size Steel Bismuth Tung-Iron Tung_Matx Chilled Pure Lead Heavi-Shot -Shot Type Drift - The horizontal drift from a cross wind. Some radiates out from the projectile, sending ripples of energy through soft tissue, rather than using all of its force to knock the bad guy backwards into that watering tough or stack of conveniently placed barrels. Enter Weight: grains: Enter Velocity: feet per second . Who are we? You already know that you have 3 mils to the dot. The free recoil energy is the work that must be done to control the firearm upon firing. I guess I am going to be the guy that gets bunched up on your velocity/caliber claim. Here goes: velocity isnt important. Fire. Using the function: Watch on. To calculate the ballistic coefficient from range data, two velocity measurements and the distance between them are required. Of course a chronograph is the only way to get. Your information will never be shared and you can unsubscribe with one click at anytime. Pure math, man. One foot pound (sometimes written as ft-lb) translates to the amount of kinetic energy it takes to move a one-pound object one foot. Although we dont always like it, a hunter can shoot an animal and let it run off a short distance to expire. However, for this to occur, the barrel would have to be impractically long. Thats .1 mil at that distance, which makes 1 mil equal to 50cm. Were at 5.6, so too slow. I had not thought much about that before. Muzzle Energy will be rounded to the nearest whole number. Muzzle energy isnt something that can be measured with radar guns or impact targets. In fact, math is in virtually every angle of shooting. As always, its important to remember that at the end of the day there is no substitution for accuracy. You now have a range card that you can go in and edit at will tailored to your individual rifle. The free recoil energy is the work that must be done to control the firearm upon firing. It's based on the assumption that a rifle will impart the same amount of kinetic energy to both bullets. Muzzle energy is the amount of energy a bullet carries right out of the barrel. The load Ive found most accurate is 37.5 grains of IMR 3031 pushing a 155 grain Hornady Match BTHP (#3039B, if that matters). Take your standard duplex, zeroed at 100m, and hold it dead center. Pressure isnt as critical as people think, either. Use only your reticle, which should have real mils on it. Enter 100m as zero distance. They are about like guys in F Class. It all depends on what you consider long range to be. Ad & Review Requests 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. This is something that is known as muzzle velocity, and it is a very important factor in determining which bullet cartridges will give their best performance at any given distance based on their weight and speed.. Just enter bullet weight and velocity, and this handy foot pounds of energy calculator will return a muzzle energy value, in foot-pounds of energy. Converting an AR-15 to fire 300 Blackout is as simple as swapping its barrel. Multiply the product of the weight of the pellet (in grains) times the square of the velocity and divide that number by 450240. 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. Keep it simple. 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. Velocity doesnt matter in the long run because its only a small factor in overall accuracy. Interval: Output solution distance i.e. Youll discover that you will certainly want a temp-stable powder like Varget. The standard deviation (aka "SD") is a measurement that shows how much variation from the average number exists in a sample. Its easy to understand why we get so deep into the numbers. It may not display this or other websites correctly. Form factor = 0.719 Muzzle Velocity (ft/s) Make note of this. You get the drill. I would like to shoot longer ranges, but I only have about 300 yards at the longest. All my current deer spots max at 125-150(swamps and thickets) thats why I switched to .300 blackout exclusively. Data entry. | 115gr | 1140 fps | 332 |, Thanks again for using our free muzzle energy calculator tool. A large target , painted flat white rigid cardboard or plywood , about 4 x 8 . charge. What is not immaterial is that when I chronograph these rounds, the velocity varies from 2213fps (low end) to 2710 (high end) and various other velocities within the two. For the record, my complete rifle is about $3000, which isnt much these days. Even within AR-15s, muzzle velocity might be very different from gun to gun. Go to the next section and enter atmospherics. . Heres where it gets interesting. I never hunt with regular hunting bullets. Because we dont know it is 2400 yet, we enter 2500 first. That carries ~400fps over your 13.5 configuration. Crimpled ? 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! Our goal is to make science relevant and fun for everyone. I have a responsibility to this site to tell the truth about guns, and sir, the truth is I wont write what I truly feel about you because I wont stoop to the strata you occupy. It's not perfect but it will get you much better results than this simple calculator. This is the number placed into the ballistic computer as your muzzle velocity. After its initial release onto the commercial market the 7mm-08 Remington gained popularity amongst shooters for the rifles quick handling, accurate . Click Here to open in small window. The real variable in long range shooting is wind, nothing helps you negate its effects better than a high BC bullet with good speed. Because we don't know it is 2400 yet, we enter 2500 first. But that is immaterial. 6. I push 2815 fps with a similar load to the one you mentioned out of my 26 308 (disclaimer on that in a second). Simple is not always better and when it comes to making hits and winning matches, I dont ever want to walk rounds on. To get to 300m, I need hold 2 mil below my 100m zero. These numbers only indicate projectile performance as it leaves the muzzle. More about Kevin and links to his professional work can be found at www.kemibe.com. Using the 80 grain load (basically is 1.5X caliber) I add 8.125 (FPS Factor) X 15 (barrel length over 24, up to 39) and subtract 5.75 (FPS factor) X 2 (2 inches over 40 barrel length) Starting book velocity of 1560 FPS plus 110 FPS = 1670 FPS. Joined: Fri Nov 30, 2012 6:25 pm. Let your fellow shooters know share this article using the Facebook, Twitter and other social media icons below. Sight Height (in) . Now for some constructive criticism. grains. Also, Microsoft Paint. If you click one of these links before you buy, we get a small commission while you pay nothing extra. 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 . I appreciate and use the JBM site regularly as well. Since we saw the impact at 4.5 or so, we hold the 4 mil line on your target center. You literally cannot avoid it. Actually look down your crosshair and see where the mil lines are. It isn't difficult to calculate the average pressure required to push a bullet out the muzzle of a gun at a certain velocity. Trust me when I say that Ive been teaching people for years and this method is what I use to instruct at the range. Okay, so now you have that. 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. Yes actually and Ill elaborate on how to figure that out in a minute . Save my name, email, and website in this browser for the next time I comment. Ah, 2400. To calculate recoil energy: Obtain the momentum of the bullet by multiplying the mass and velocity of the projectile fired. 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. Ahh, the science of walking it in and then running calculations backward. For a better experience, please enable JavaScript in your browser before proceeding. The folks at Precision Rifle Blog did a How much does it matter? series, and extrapolating their work from that, a 400fps advantage translates into a roughly 12% increase in hit probability (assuming identical conditions and shooter ability). Go buy Magpuls Art of the Precision Rifle. 7. Register today and take advantage of membership benefits. Because the length of the barrel greatly affects both the velocity and energy generated at the muzzle, the figures touted by the manufacturer arent precise and certainly wont be specific to your particularly firearm. I have mine memorized at 300 , 500 and 800 yards and can do a 10 inch gong in 3 shots almost every time . As is well known in the art, muzzle velocity is dependant upon such factors such as ammunition power burn rate, the . Muzzle Velocity and Down-Range Velocity Ballistic specifications for specific cartridges are based on measurements from tests performed using SAAMI specifications. Group size at 100 yards is just under half an inch in both directions (horizontal/vertical), so I say its half an inch. Is there a calculator out there somewhere on the interseine for estimating black powder velocities? Muzzle velocity and energy are often stamped right on ammo packaging. Death comes when the brain is deprived of oxygen. Facebook Nope nope. By continuing to browse our website you agree to our use of cookies.
