But I can sorta verify bcs by measuring at the muzzle and downrange (Superchrono downrange) and calculating from those values. 3. Believe it or not, these are two very different things. Is there a calculator out there somewhere on the interseine for estimating black powder velocities? So what do us normal guys who dont try out fifty handloads in one sitting do? 1000 is an imaginary landmark in rifle accuracy. You'll need to Sign In or create a Ballistix Account if you'd like save your calculation data. This number can be used to get a rough idea of a rounds destructive potential. I have a real-world rifle for real-world uses and it still does .1mil at 100m all the way to 1000m and Ive used it on animals and targets alike without issue. Before that, Id interpolate ballistics tables in the back of reloading books. Watch where it impacts next to the target. 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. Definitions. What Im about to say will bunch a lot of shorts in a lot of places. Once you've completed the form click the calculate button to generate your ballistic compensation drop chart. Chronographs can be had for around $100 and they definitely have their place. For the record, the bullet is the 150 grain Federal Fusion. When talking about bullet kinetic energy, the word muzzle energy is often brought up. There you have it. This Airgun Energy Calculator is a simple widget designed to take the velocity of a projectile (bb, pellet, dart or bullet), its weight in grains, and calculate the foot pounds of energy (fpe) at the muzzle. Enjoy! Once a baseline is established, you can alter it at will to match your conditions. 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. Simple is not always better and when it comes to making hits and winning matches, I dont ever want to walk rounds on. just because it's impractical for hunting or target shooting is not a valid reason to dismiss the need for sufficient velocity. Max Range: The furthest distance you want to be represented in your trajectory output. The email address you entered is not valid. Go back to the range or set your cell phone down and set up a target at a random distance300 yards900whatever. 2. I like their stuff because I get it, but I have a hard time agreeing with some of their ideas. The 300 Blackout's .30 caliber bullet can be made especially long, and as the result may weigh up to 220 grains quadruple the weight of the typical 223 Rem round's. So heavy a bullet conveys a subsonic muzzle velocity and correspondingly softer report. One of the downsides to using a ballistic calculator is the before vs. after effect. Look it up. Pressure isnt as critical as people think, either. Notify me of follow-up comments by email. Dont under estimate the importance of #7 . We appreciate all of your support and use of our site. You need to pay attention to velocity in two aspects, and they are: Then.

In fact, the faster an object is moving, the more kinetic energy it has. A comfortable solid platform . Getting ones load standard deviation down into single digits of fps is challenging, but it can be done. Projectile motion definition. Elmer's favorite load of 22 grs. I dont trust chronographs but I do trust math. Copyright 2023/ Privacy Policy / Terms & Conditions. Interval: Output solution distance i.e. Get the very best gear you can afford and make the most out of each shot. And you can do it in only a few shots. Data entry. Velocity doesnt matter at all. There will be a day when even a FFP mil/mil is obsolete, but were not there yet. Better put on your shades while reading this because your future is about to get bright. Doesnt this mean your method of attaining MV may yeild a wrong value for MV? . *yikes* hope no one paid money for this advice. It is by no means a calculator, as it uses averages and gives ballpark figures. So, your practice shooting will be similar to what you will experience if you fire your weapon in a defensive situation. Count the number of mils to the wide part of your duplex and make note of it. This calculator will produce a ballistic trajectory chart that shows the bullet drop, bullet energy, windage, and velocity. Take that meter stick and make lines on your target. Your 308 load moves approx 46 more at 1000 yards than my .260 load in a 10 mph wind. . lb Muzzle Velocity ft/sec. than trying to say simply if a bullet is stable or unstable. You still dont know jack at the end of the procedure. by dellet Fri Oct 21, 2016 9:25 pm. The future and the technology in it isnt scary. Is that bullet even moving? Blackhorn 209 posts 1,900 fps of muzzle velocity for 100 gr. Let MV = The Muzzle Velocity calculated from the Chronograph Velocity. Converting an AR-15 to fire 300 Blackout is as simple as swapping its barrel. You're not currently signed in. If you are a hunter, youve probably shot an animal that didnt drop in its tracks. A lot can happen between the muzzle and target impact. Calculating Muzzle Velocity and Trajectory With Five Shots (Or So). To use this tool, enter a bullet weight and velocity for a known load. You can hover over the question mark icon on any field to learn more about how that field will impact your calculation. Too fast. As a rule the faster the muzzle velocity the shorter the bullets time in flight and there for a flatter trajectory and less drop. Enter Weight: grains: Enter Velocity: feet per second . 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. What matters more is what the projectile does once it strikes the target. At best it should be considered a rule of thumb or an estimate. If 22 barrel is still too big for maneuvering, I have far more appropriate tools at my disposal. Move your reticle over to your target and hold the nearest round mil onto the dot in the middle of your target. A decent high power rifle with a quality barrel , I enjoy my Noreen BN 36 for 500 yarders . .. Also, you say twist direction and rate are important but sight height isnt. And even when there is, the vast majority of cops and servicemen will stand with us, not some politician like king obama. 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 . A private range . Solve the problem using pen, paper and calculator. Kevin Beck holds a bachelor's degree in physics with minors in math and chemistry from the University of Vermont. You should carefully consider weight retention and projectile expansion or fragmentation as well. That happens to be the longest distance at my local range. Your information will never be shared and you can unsubscribe with one click at anytime. [emailprotected] Make note of this. Its reactive and gives instant feedback. I figure that is to much deviation if I have been careful reloading, 168gr bullet at 2400 fps? The sensor relies on measurement of magnetic field induced voltages which are unique as the ammunition leaves the muzzle . It looks like that first shot may have been down 4.5 mils. So, real world performance can vary greatly. Free Ballistic Calculator. Its about building a range card based on data. Go back to the line and look through your scope. 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. 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. Units of Measure . Those centimeters are what you want. Death comes when the brain is deprived of oxygen. Youll NB if you read these tables what Im saying is true it is very infrequent for the hottest load that Lyman has tested to also be the most accurate. Muzzle energy isnt exactly precise or the most important aspect of ammunition performance. Comments like this are why people dont like this community. With the first charge the muzzle velocities for the short and longer barrel were 1,095 fps and 1,231 fps. Never go full metric. 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. Re: Muzzle velocity and barrel length. Ive been on enough hunts to know it doesnt really matter in real life. 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. Bullet or shot weight (gr) 1 oz = 437.5 gr. A ballistics calculator, primarily for round ball ammunition used in muzzleloading arms. To put that into perspective, I would need to step up to a 300win mag to gain a similar advantage to my current setup. Bullet Energy Calculator. Chronologically, this takes placei. Diameter. Leave it. Instead, it is a rather ethereal figure that can only be computed using the previously mentioned formula. 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. Crimpled ? Muzzle 25 50 75 100 125 150 175 200 225 250 Velocity (fps) 1900 1843 1787 1732 1679 1628 1579 1531 1484 1439 1395 Kinetic Energy (ft lb) 1723 . + 1 inch at 50 yards, 0 at 100 yards, -5.2 at 150 yards, and -15.3 at 200 yards. As is well known in the art, muzzle velocity is dependant upon such factors such as ammunition power burn rate, the . Something about lots of spectators makes my finger jump . An important factor in any calculation of muzzle velocity is going to be the energy output - power - whatever you want to call it - of the powder you are using. You want the specs of these two loads to match. Many gun people will even use the term interchangeably with stopping power. But is muzzle energy important? So lets just go forward with this example. You now have a range card that you can go in and edit at will tailored to your individual rifle. Muzzle energy is the amount of energy a bullet carries right out of the barrel. 5865 S 77th Street The Accura LR boasts a 300-yard shooting capability by providing better velocity through its 30" Nitride-treated Bergara barrel. I wasnt sitting with you when you took your shots so I will take your word for it though. You can use those programs the same way. No amount of calculation is completely accurate. Zero Range. If Im not mistaken, Travis Haley has shot the 300 BLK out to 1,000 yards. As detailed in other articles Ive written, most people never shoot beyond 300. Muzzle Energy will be rounded to the nearest whole number. Abstract. This is just the sort of guy thatd buy an RV and then bitch about the cost of gas. Plus, Id never shoot an animal at that range and on targets it doesnt matter. 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. Lord, that .06 is gonna kill us. Our goal is to make science relevant and fun for everyone. Hopefully this proves useful! One thing Ill unhappily confirm: chronos are a pain and not reliable. To calculate the muzzle velocity, a velocity measurement, the ballistic coefficient and the distance from the muzzle to the measurement point are required. 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. 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. Ballistic specifications for specific cartridges are based on measurements from tests performed using SAAMI specifications. I dont doubt you Josh , it just doesnt appeal to me and Ive been a reloader for 25 years . Just enter your bullet weight below and its velocity.

You can have a super-fast load and have it be not-so-great. A powerful .22 caliber air rifle such as a Benjamin Discovery or Marauder fires a 14.3 grain pellet with a muzzle velocity of approximately 900 ft/sec. Def.) As the bullet travels down the barrel, propellant gases build pressure and accelerate the forward motion of the projectile. After its initial release onto the commercial market the 7mm-08 Remington gained popularity amongst shooters for the rifles quick handling, accurate . The standard deviation (aka "SD") is a measurement that shows how much variation from the average number exists in a sample. Ive found that speed isnt key to accuracy at practical ranges. Thanks for the article. The website will also let you include a zero at Point Blank Range, which is great for guys with the duplex reticles. It just isnt. 2023 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. Good stuff Josh. Click Here to open in small window.

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. I like the consistency of the .308 myself, but it definitely peters out at long range. So the differences for the 21/2 difference in barrel length were 136 fps, 144 fps and 153 fps . As gun people, we often become obsessed with ballistic data, particularly with energy and velocity. What We Use Exit out and be sure to accept your MV. I consider long range in the field to be 500m and out. The UK legal limit for Rifles is 12 ft/lbs and for Pistols is 6 ft/lbs. Muzzle Velocity. Ralston, NE 68127 It meters nice and burns clean. Youre good to go after checking range in meters, so press calculate. Save that information. Although we dont always like it, a hunter can shoot an animal and let it run off a short distance to expire. Gravity pulls a .22 the same as it does a 338, so having put a value . Watch for splash and impacts. 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. A low number indicates most numbers are close to the average.
