Ruger 77 inline with 209 primers. Twist is 1 in 28in, 50 cal. Anybody shooting one of these? My brother just got one. Previous owner said it was good for about 5" at 50 yards. no better. He was shooting a sabot of some sort, bullets with a little cup attached. I can't believe this gun won't shoot 2 inches at 100, or close to it. Will be shooting either 2F or Cartridge. [U] have several molds in this size. Any advice would be helpful. This is a bit out of my wheelhouse. thanks in advance
ps what lube/wad is working. I generally use 50/50 crisco/beeswax, b ut I have a lot of bore butter and/or wonder lube on hand
