My question is:
In the simplest terms possible, what is it about one gun that can make it fire a bullet further and faster than another gun firing the same ammo?

PE = M g h
M = w/g = (300 gr)/[7000 gr/lb 32.2 ft/sec2] = 0.00133 lb sec2/ft
PE = [0.00133 lb sec2/ft] * [32.2 ft/sec2] * [6 ft] = 0.26 ft-lb
KE = 1/2 M v2 + 1/2 I w2
KE = 1/2 M v2
KE = 1/2 M v2 = [0.5] [0.00133 lb sec2/ft] [3000 ft/sec]2 = 5985 ft lbs
KE = M v2/450800
450800 = 2 * 7000 * 32.2

That's not the sort of answer I'm looking for.
