I did find some really good recipies this last week. My rifle seems to like 4350 powder. I was using nosler 165's and hornady 180's they grouped great! The rifle is just getting broke in as well. The 165's chronographed at 2900 and the 180's at a bit over 2800. I was very pleased! I cant shoot very well, but I ended up getting about a 2inch group of five. For me thats real good! Any other good powders? EJ
