So, I have an idea. I was wondering about 4 bore's. I want to build a 4 bore and did a few searches and found countless 4 bore builds on other forums and a video series on a builder who has built 2 of them. Everything I could find online was for black powder. Does a 4 bore smokeless barrel exist? Maybe the pressures spikes are too much for standard barrel metals, I don't know? But figured I'd ask here!
