2. .50 Beowulf - Wikipedia

   en.wikipedia.org/wiki/.50_Beowulf

   With normal bullet weights between 300 and 400 grains (19 and 26 g), overall cartridge length shorter than that of an AR-15 magazine well, and holding to pressures of 33,000 psi limited by the AR bolt strength system, [2] the .50 Beowulf is best described as a low-velocity, heavy caliber, making its ballistics roughly equivalent to those of ...

3. List of AR platform cartridges - Wikipedia

   en.wikipedia.org/wiki/List_of_AR_platform_cartridges

   If the bullet velocity is capped at 1,000-Feet Per Second / FPS in order to subdue the noise of firing, then the impact can be improved by increasing the weight of the bullet. The 357 Auto can be loaded with bullets in .358-caliber, while still fitting within the AR-15 COAL of 2.260". Bullet weights are currently available between 225gr-310gr

4. Table of handgun and rifle cartridges - Wikipedia

   MV: Muzzle velocity, in feet-per-second; ME: Muzzle energy, in foot-pounds; P: Momentum, in pound (force) (lbf) times seconds. [1] A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters ...

5. Taylor knock-out factor - Wikipedia

   en.wikipedia.org/wiki/Taylor_knock-out_factor

   The Taylor KO factor multiplies bullet mass (measured in grains) by muzzle velocity (measured in feet per second) by bullet diameter (measured in inches) and then divides the product by 7,000, converting the value from grains to pounds and giving a numerical value from 0 to ~150 for normal hunting cartridges.

6. Terminal ballistics - Wikipedia

   en.wikipedia.org/wiki/Terminal_ballistics

   Bullet parts: 1 metal jacket, 2 lead core, 3 steel penetrator. Terminal ballistics is a sub-field of ballistics concerned with the behavior and effects of a projectile when it hits and transfers its energy to a target. Bullet design (as well as the velocity of impact) largely determines the effectiveness of penetration. [1]

7. .50 caliber handguns - Wikipedia

   en.wikipedia.org/wiki/.50_caliber_handguns

   The .500 Linebaugh utilizes a bore diameter of .500" with the corresponding bullet diameter of .510", the same as the .50 BMG and other .50 caliber rifles, while the .50 Action Express, .500 S&W Magnum, and .500 S&W Special use .490" bore diameters and correspondingly smaller .500" bullet diameters. The smaller .500" diameter was further ...

8. .45 Raptor - Wikipedia

   en.wikipedia.org/wiki/.45_Raptor

   The 45 Raptor (11.5x46mm) is a rimless centerfire cartridge developed for the AR-10 semi-automatic rifle for medium and large game hunting. Compared to similar big bore cartridges designed for the AR-15 – such as the .450 Bushmaster, .458 SOCOM, and .50 Beowulf – the 45 Raptor offers higher velocity bullets, a flatter shooting trajectory and the ability to reliably feed hollow point ...

9. .50 Alaskan - Wikipedia

   en.wikipedia.org/wiki/.50_Alaskan

   Since the rifle was designed for use on Alaska's great bears, Johnson cut 720-grain (47 g) boat-tail .50 BMG bullets in half, seating the 450-grain (29 g) rear half upside down in the fireformed .50-caliber case. It didn't take Johnson long to find out that the truncated-shaped "solid" would shoot through a big brown bear from any direction ...
