Wow, this is great stuff, thanks all. The reason for my post is that I am getting a 16b H grade Lefever with twist barrels this week, an unmolested, 6.5lb., 28" short chambered gun that will need a re-brown and metal refinish at some point. I'll post pics when I get it. My last Lefever 16 had steel barrels, so this will be my first go-to gun with twist barrels. I do belong to the 16ga. group and society, and can't wait to start roll crimping some low pressure 2.5" loads. I already have tons of Federal 1 oz. game loads I would love to be able to use, but I might trade them off or get a cheap pump gun or single shot to shoot them in.
