I agree but it is unusual to me that weapons development in the last 100 years has developed around the brass cased cartridge concept. Its the tail wagging the dog. And I've seen the rocket guns and caseless projectiles that are electronically ignited. The caseless rounds worked great. No bolt, no ejection, no recoil, no jamming, double & triple projectiles, no smoke, very little noise.
