Have a recent acquisition of a shiloh sharps 38/55 with a 34 inch barrel, 1 in 16 twist. Cannot get it to stabilize, have tried 2 different weight projectiles at 320 and 365 grains and different powder loads from 43 to 49 grains of Wano 2p.
I have more than 30 years of Black Powder experience with Gibbs, 45/90 Remington Rolling Block, 40/65 Sharps. All using my own cast bullets with good results, winning many events out to 1000 meters.
Have used 20:1 and 30:1 alloys Plus 365 grain BACO Creedmore and 320 grain CBE molds
Please Help
