I bought a quad pin roller and tried it today for the first time. Once I warned it up on my first shell. I pushed down to hard before I heated it up and dented the hull. The second turned out great!
I even rolled a couple thst I hot glued the cards in place. I needed a little more hull length but I got them to roll. It as a little messy as the hot glue melted onto my roller. The hull on the left was my first try. After I did a few of my uneven RST shells (that shockingly turned out pretty good) I re rolled it a little tighter. It chambers just fine...it’s just not a pretty.
I actually traded some lead ignots in clip on wheel weights to a member from another forum recently for #5 shot. The shot he sent me was lead BB. So I will be using the only shot I have which is the BPI nickel plated #6’s. They normally knock a turkey flat under 50 yards in my browning gold. Hopefully they do just as good with lower velocity black powder loads.
