Blackdiamond..
Using 2 plugs or 100gr of pirodex and a 240gr XTP Hornady's groops well at 50 and then @ 100 and 150 moves right about 6"-10" respectively. Tried 150 gr and same result. Think I get better performance out of strait powder (pirodex FFG)but didn't get to revert to it tonight. Iron sights (R) is cranked far left to compensate but almost like its spiraling funny? Will go back Tuesday to retry but need for NH hunt this coming weekend. 5-7MPH crosswind at time, would that push that that far?
