When I have 230 grain bullets in my full-size Para-Ordnance, the bullets alone weigh over half a pound. 15+1 X >1/2 ounce apiece. 218.75 grains is 1/2 ounce. 16x230 = 3,680 grains = 8.41143 ounces, just for the bullets, not counting all the brass and powder. That's one reason I like 165 grain bullets. 16X165 = 2,640 grains = 6.03429 ounces, 2.37714 ounces less. The alloy frame pistol loaded with 14 rounds of ball ammo weighs as much as a steel frame 1911 with 7 or 8 rounds. Lighter bullets can take a couple ounces off each mag full. I usually have 2 spare 15-round mags with me anytime I have the pistol on me, so the lighter bullets save me about 7 ounces over 230 grain bullets.
