Stubble,

I am trying different powders with different bullets. I have shot two groups with that load, the other was about 1 inchto 1.25 I am tryin all sorts of powders. What I like about the 30-378 is you can push the heavier bullets a little faster. IMR 7828 was my best powder with a 180 gr. So far I have tried RL25, IMR 7828, H50BMG, and H5010 with 180 grain Barnes TSX and 200 grain Barnes TSX.
