ya missed the part where I said 'except' a slug

force = (mass) x (acceleration)squared

so more velocity puts exponentially more force or energy into a projectile than a similar increase in mass.

see, told you we'd insite a riot if we dared talk about 12g rounds! hahahaaa

good points from everyone so far though. I have to agree that the 12g is one of the most versatile guns out there just by switching ammunition or barrels.

growing up a rifleman, gotta stay with a rifle if I'm down to one gun. you wouldn't do too bad with the shotty though.
