I wanted to edit before anybody said anything. The 117 grain Sierra were shooting 0.5 MOA out to 500. I don't want to seem crazy. I first used the 100's but found the 117's shot better at distance. Now with the berger i'm trying to compensate a little more for my inability to read the wind.
I'm thinking about jamming them and working up powder because none of the groups I shot were spectacular, so maybe I need to tweak the other major variable first.
As I've said in another post I want to try the bergers in my 264WM but I wanted to use them in something thats a little bit less of a fire-breathing powder eating monster. (albeit not that much less of one)
