When the 77 gr SMK was fired from a 16 inch barrel, the bullet didn't even reach 12 inches in ballistic gel. When fired from a 14.5 inch barrel, it went more than 15. My theory is the more penetration the better. Right now I'm using a 20 inch barrel. Should I go to something shorter for more penetration?
