20 Ga. Weak? no way My hunting partner took his Rem. 20 ga. 1100 and added a rifled barrel, scope, and shoots the new Remington ULTRA sabots.Look em' up they have better than balistics than a 30/30 at 100 yds. His 12 stays home, he said his 20 is as accurate at 100yds as anything he has found and it doesn't have the recoil a 12 does. Deerhunter 515 referenced these slugs.... 385 grains-1,900 fps at the muzzle.
