Penetration and Power-What are the comparative penetrations and powers of the .22 caliber long rifle cartridge and the .22 caliber Winchester Automatic rimfire cartridge? Which is the most powerful?
The automatic cartridge, shooting smokeless powder, and a 45-grain bullet has a penetration of five 7/8 inch pine boards; the long rifle cartridge, shooting black powder, and a 40-grain bullet has a penetration of four of these boards. The automatic cartridge is considerably more powerful, however, as it takes up some powder in working the mechanism of the rifle.
