Crazy idea came to mind! What if I bought a 20 gauge moss shockwave. SBS tax stamp it. Have vang comp do the barrel treatment, except no porting because I don’t think that tightens the spread. And then just use regular #1 buck in it.
The main downsides to 20ga I always read are lack of the good stuff like flight control. Well if you have the vang treatment maybe it doesn’t need flight control?
The main reason for this to me is that the shells are smaller so in some kind of survival scenario, you could carry maybe double the ammo idk.
Twist in this idea is not tax stamping and just brace it.but idk how well braces work on shockwaves.
