Ballistics is an odd, but fascinating science, and it can be intimidating to go too deep. This means you have the option to read your magazine on most popular phones and tablets. In this case, the Form Factor becomes 1.0 and the BC equals the Section Density.Read more , This But that one- mile-plus first shot GONG is addictive!!! The password should contain at least 8 characters with at least one number or special character. When doing pre-purchase research either on the web or at the store, the increased performance of the ELD Match and ELD-X bullets wasnt always realized in a head-to-head BC comparison.

These bullets also feed very well from the detachable magazines being used by most long-range semi-auto and bolt-action rifles. The Ballistic Coefficient of Rifle Bullets - CHUCKHAWKS.COM This also applies to the shooter's skills. Instead, the BC is best used as a comparative number between different bullets. Articles may contain affiliate links which enable us to share in the revenue of any purchases made. Ballistic Coefficient is essentially a measure of air drag. The new Sako Finnlight II sports an innovative stock and Cerakote metal paired with the terrific 85 action. Ballistics Coefficients - Rifle 1450 .224 50 BlitzKing .142 .248 @ 3300 fps and above.243 between 2650 and 3300 fps .232 between 2050 and 2650 fps . If you look at the G1 bullet image, youll see that it resembles a common projectile shape from the 1800s era, give or take. Mag. BC will help you determine the effective range of a projectile by taking drag into account. As an example, the Hornady 6.5mm ELD Match bullet has a BC of 0.646 for the G1 drag model but a BC of 0.326 for the G7 drag model. Two measurements that help define the downrange performance of a bullet are ballistic coefficient and sectional density. It's when game such as elk, moose, caribou, mountain goats and the bigger bears are on the menu that bullet integrity becomes critical. Built to maximize long-range performance for target shooting, Logan Schamburg from Blackjack bullets says the ACE Match bullet works very well on big-game animals too. How much a bullet slows down depends on the density (thickness) of the air and the efficiency of the bullet. google_ad_client = "ca-pub-8417283882784443"; Then youll repeat the process. Dont chase a particular BC. Since the primary concern about BC is for long range shooting, shotguns and handguns need not apply. There are a few things you need to understand in order to make a valid comparison. But unlike standard factory fare, the Cutting Edge bullets are intended to start . Let's compare the practical ballistics of a traditional flatbase bullet with a modern high-ballistic coefficient bullet when both are zeroed at 200 yards and fired in standard sea-level conditions. The Standard projectile is the base we establish to gauge ballistic coefficient. Access features of the Reloading Handbook on your mobile device with the Reloading App. Round Nose bullets have the lowest BC. Although a faster bullet isnt necessarily more accurate, its affected less by gravity and wind. If they penetrate only 12 or 14 inches (inhibited by that same massive frontal diameter that's causing such dramatic tissue destruction), that's usually adequate. Our first offering in the Blackjack Bullets lineup is the 25 Caliber 131 grain ACE Match bullet with an outstanding 0.330 G7 Ballistic Coefficient (1000 yd Average BC) tested on the Oehler 88 System.

To throw a little light on the subject (and out of my own curiosity), I recently shot a selection of eight of my favorite bullets into 10-percent gelatin at 50 and 400 yards. They will also sometimes require a faster twist rate. Available Calibers: 6.5mm, .277, 7mm, .308, and .338. Granted, for 80 percent or more of the game (whitetails) shot by Americans, bullets don't really need to hold together and penetrate particularly deeply to provide clean, humane kills. The longer they have to act on your projectile, the more of an effect theyll have. Contributing Editor for RifleShooter Magazine, Brad Fitzpatrick gives us a review of this modernized version of an iconic favorite.

My next preferences is Sierra, Swift and Hornady. They need to be able to factor in how far the wind will move their round, bullet drop, and velocity at different ranges and it all ties back to the BC of their particular load. There are just so many factors to consider, many of which the manufacturer cant know, including atmospheric conditions, the drag created by your rifling, and more. They are also made with the longest possible hybrid ogive and are a tad bit heavier than common bullet weights associated with each caliber.

All Rights Reserved. For 2020, Federal will be offering a new line of ammunition called Terminal Ascent, which uses a bonded bullet with a solid-copper rear shank to penetrate deep on close targets, and a polymer tip to initiate expansion at velocities 200 fps slower than comparable designs. G1 is most commonly used because its the old standard and the industry has not adapted to the more modern incarnations. Due to the sensitivity of BCs to velocity, it can highly skew the comparison. G1 Ballistic Coefficient - this is the older system of measuring BC and is more suitable for flat based bullets, although many bullet manufacturers use this coefficient for boat tail bullets as well, as it is more commonly found. Its that simple. Red Oak, White, or Chestnut for Deer Herd?

First Focal Plane vs. Second Focal Plane Scopes Explained: Which is Best? It details drop, time, energy, velocity, range, and does so in . Conversely, if we launched the two objects in a vacuum (no air resistance), then both would continue to fly at the same speed. This was done to provide the most usable BC from a trajectory prediction standpoint. The ELD-X (Extremely Low Drag - eXpanding) bullet is a technologically advanced, match accurate, ALL-RANGE hunting bullet featuring highest-in-class ballistic coefficients and consistent, controlled expansion at ALL practical hunting distances. 10 Best Long-Range Rifle Cartridges Ever Made - Game & Fish When comparing BCs of different bullets, it is important to use an apples-to-apples approach. Now, to save you the time and effort I put in, Im going to share just about everything I know about ballistic coefficient. Note that with bullets of the same weight and style, such as the 100 grain .243" and .257" bullets or the 150 grain .311" and .323" bullets, the smaller diameter bullet always has the superior BC due to its better sectional density. Americas oldest Second Amendment News outlet.

The definition according to Wikipedia is, "the ballistic coefficient (BC) of a body is a measure of its ability to overcome air resistance in flight.". With that said, the number the manufacturer gives you is a rough estimate. If it asks for a G7 number, use the 0.326 figure. Weve got a big wide object pummeling its way through the air towards the target. Ballistic Coefficient (BC) values at Mach 2.25 (2512 fps @ ICAO Standard Atmosphere) should be used when comparing to other published BC values within the industry. Thats because the BC varies with speed. In the world of ballistic coefficients, a bigger number means that a bullet flies more efficiently.
