For a Ruger, and any specific purpose? Have started reloading for a Ruger and have good luck with Hdy .309 90 grain xtp. Win brass, Fed small rifle primer and h-110 charges from their manual. The specific pistol has a lesser than usual firing pin protrusion, and had to be careful about other older cases and deeper primer pockets and min case lengths. Winchester cases and not trimming to min length fixed the problem, but may be common to other Rugers?
Even with Hornady 110 fmj, it is a blast to shoot. The hdy fmj were also extremely accurate, maybe the exposed lead base?
Pistol is extremely accurate, but am doubting regular 110 grain soft points ability to expand.
