I have made some new slugs for my .30 Cal. Wolverine, after many tries I have a slug that will outshoot the JSB 50 grain pellets. I had been told that the gun would not do that because of the "choked" barrel. When it warms here I can stretch the range some and get out the chronograph. The bullet is an 80 grainer and my third try at this weight, I have two other molds that I tried at around 80 grains but no cigar. Slugs cast med. hard would not chamber so I tried them dead soft and with lube and viola!!
