Miller twist rule is a mathematical formula derived by American physical chemist and historian of science Donald G. Miller (1927-2012) to determine the rate of twist to apply to a given bullet to provide optimum stability using a rifled barrel. [1]
In both the open and standard rifle divisions, minor power factor is dominating due to less recoil, and 5.56×45mm/ .223 Rem is a common caliber. Ammunition loaded to major power factor such as 7.62×51 mm/ .308 Win has a bigger recoil impulse, and is regarded as having an advantage on stages with targets at long range.
The rearward energy of the firearm is the free recoil and the forward energy of the bullet is the muzzle energy. The concept of free recoil comes from the tolerability of gross recoil energy. Trying to figure the net recoil energy of a firearm (also known as felt recoil) is a futile endeavor. Even if the recoil energy loss can be calculated ...
The following are base examples calculated through the Handloads.com free online calculator, and bullet and firearm data from respective reloading manuals (of medium/common loads) and manufacturer specifications: In a Glock 22 frame, using the empty weight of 1.43 lb (0.65 kg), the following was obtained:
The wash-sale rule applies to both you and a spouse as if you were a unit. For example, you may not claim a loss while your spouse re-buys the asset within the 30-day window. This rule also ...
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. [2] Chg: Propellant charge, in grains; Dia: Bullet diameter, in inches; BC: Ballistic coefficient, G1 model; L: Case length (mm)
The recent self-checkout issues have led some to speculate that companies are adjusting access to their self-serve stations in response to customers forgetting to scan or pay for their items, as ...
