I managed to put one mag through it last night before the rain came, 3.3 grains 700X with 122 grain LTC. Stretched the distance out to ten yards, the fading light would not permit anything greater. I managed to bullseye it a couple of times but also made some nice clusters high and to the left. On the plus side there was not a hint of leading in the bore of the factory barrel, if anything it looked somewhat cleaner than the FMJ loads did. The Storm Lake barrel hasn't showed up yet, should be any day now.
I went ahead and ordered some things I think will help the situation based on my experience with the Ruger SR9c. An extra power striker spring should help the mushy, stagey, trigger pull. The 6.1 mm rear sight should help bring the POI down some. I can trim the bottom of the notch until it is perfect for me. Also, the gen. 4 dual recoil spring is just plain overkill for the mild lead boolit loads I shoot. I ordered a factory gen. 3 recoil spring and adapter for same. Hopefully this stuff will get it shooting right!
