Honestly, I'd need to put more rounds down range and try to be a bit more "qualitative" with my analysis before I could give a personal opinion on that. There's obviously the shootablilty aspect, the carry aspect (ounces==pounds, pounds==pain,) and the impact performance aspect, that all have to be factored in to the equation.Without significantly less recoil, I don't see any reason to go with the 20ga. Do you agree?
I promise to report back when I have more to present.
