Lookin good Sax. I responded on the other forum too.

To me it looks like the GM likes a dirty bore as both groups had the #1 shots pretty much in the same area. Maybe a new powder would help keep them together but i honestly wouldnt touch a thing other than try a lower charge to see if what happens. Could have been a flinch too, never know!

That 225 is a fun bullet to hunt with too. Sight dead on @ 100 and be about 3" low @ 150yrds.
