The Absolute Hammer seems like such a simple concept--reduced bearing surfaces causes lower pressure which enables one to use faster powder to get a substantial velocity gain.....so why didn't the teams of engineers at the major ammo and bullet manufacturers come up with this first??
I know this is a rhetorical question, but I can't resist answering . . .
Because most in the firearms industry are tradition-bound and ossified, and refuse/are terrified to try something new.
