Would porting be different for a shotgun barrel if i were shooting "shorty" slugs (I think they are 1.75" long) vs. the standard 2.5-3" long slug? If so, does anyone know how much difference? Different number of holes drilled? Different angle?
The above is great advice. However, not all gas is created equal !!!If one requires porting for minis
1. Turn in man card
2. Buy a .410
Joking aside, I doubt the mini makes enough gas to matter. From what I’ve shot of them.
If one would insist, no special porting should be required. Energy is energy, gas is gas.
