Savvy Jack- I shot NRA silhouette in the 1980's with a Ruger SBH at 100 yards. I used Win. brass and primers, 27.3 gr of Win 296 and Hornady 200grJHP( not SASS legal). If I did my part it would shoot 4 inch groups at 100 yd, it was very loud and abusive to shoot, but oh so fun. I no longer have the paper targets to back this up, but I still have some of the ammo and still have the SBH.
