Gah!
Why don't we go back to 45-70's in trapdoor springfields, everyone knows that smaller rifle calibers are for sissies and won't stop a drugged up cannibal warrior from the phillipino jungles! The trapdoor is a much simpler rifle than the M16, m14, M1, 1903, and Krag rifles so there is less worry about finding dead soldiers with a jammed up gun!
For handguns lets go back to the Colt SAA. If the 1911 with 7 shots is better than the beretta with 15 because the .45 auto is more powerful, then logically 6 shots from a much more powerful Colt SAA should be superior to the 1911!
Naturally, the higher costs of the hundreds of tons of additional lead, brass, and powder can be picked up through donations from the armchair warriors who don't want to see progress in our military's technology.
