Ok tried out yesterday's loads, all were standard pressure (trapdoor level) loads and shot fine, didn't see any signs of leading at the front of the chamber and absolutely no pressure signs. Also tried some level 3 loads with 50gr of IMR 4198 behind a 250 gr Barnes tsx flat base hollow point. Holy Moly!!! Got a 1" group at 50 yrds and totally smoked three one gallon water jugs lined up for a penetration test. The only way I could "catch" a bullet was to shoot a 15" oak block and I got 9" of penetration there with the bullet tumbling and coming to rest base first. However recoil was ferocious. Now to wait for deer season so I can try em on white tails!
