Or when your neck no longer allows you to push your face down to the buttstock, and you resort to optic risers. All of that to say that you can increase the length of a barrel to a point and continue squeezing more velocity out of the shot, but at some point the bullet will start slowing down again unless you increase the available fuel to burn with a larger cartridge. Hey Jon, by popular request it seems like a 308 version is in order. You can find an email form and contact information here. A ballistic coefficient can change with reference to (1) altitude, (2) temperature, (3) atmospheric pressure, and (4) relative humidity. conditions. Enter a BC and matching drag function, or select a bullet from the library and then enter the following variables: Yellow text means the bullet has gone transonic, or under Mach 1.2. The chamber is of standard SAAMI specification in .308 Winchester and the barrel features a 1:10 right hand twist.

The 300-yard zero looks like a decent solution for combat, assuming you can always aim center mass. There is a ballistics calculator on the Norma website where you can see the parameters for various bullets, such as velocity, range, etc. The zero range isn't relevant to this calculation - it reports total drop, which is adequate for comparison purposes. Pejsa based models are clever simplifications of the point mass method that allow for greatly simpler calculations at a small cost in accuracy. The charts all clearly show that there are different impact points. It also has extensive measurements of drag data using the G7 drag function, which is the best match for today's long range bullets. AR-15s most commonly use a 1/2x28 thread pitch. Picking a solid point-blank zero to minimize the amount of holding over you need to do is important, but you also need to be aware of where your impacts will fall. Its not an exact science, because other factors influence the velocity as well. Ralston, NE 68127 Of course, more pressurized gas, used more efficiently, means more velocity. Volume 1 6.5 Grendel Reloaders Handbook, Volume 2 6.5 Grendel Reloading Handbook, .260 Remington Barrel Length? NORMA Ballistics considers this parameter and calculates the change in velocity due to your barrel length providing a more accurate result. The projectile's spin and yaw is not modeled, so spin drift and aerodynamic jump are not reflected in the calculation. Muzzle velocity refers to the speed of a bullet as it passes through the muzzle of a gun. When you look back over the history of the AR-15, youll find that we didnt just end up with a 55gr .22 bullet fired through a 20 barrel.
