The 12 gauge slug weighs in at 385 grains while the 20 gauge slug weighs in at 260 grains. The 2 ¾ inch shells produce 1850 feet per second while the 3 inch shells produce 1900 feet per second. The 2 ¾ inch 12 gauge slug generates almost 3000 foot pounds of energy at the muzzle and carries over 1700 foot pounds of energy at the 100 yard mark.
AccuTip Bonded Sabot Slug
Gauge Length Slug Wt. Muzzle Velocity
12 ga 2 ¾” 385 gr 1850 fps
12 ga 3” 385 gr 1900 fps
20 ga 2 ¾” 260 gr 1850 fps
20 ga 3” 260 gr 1900 fps
This is the only chart I could find. It is clear that the velocity is almost the same in both gauges. However, the 12 gauge slug weigh almost 68% more than the 20 gauge. Since the speed is the same, it stands to reason that the 12 gauge has significantly more knock down power. Since using my 210F, I have never had to shoot a deer more than once and, they usually fell in sight.
