[QUOTE="MagnumManiac, post: 2405179, member: 10755"] During fire forming with a 300WM barrel, I shot the best ever group at 300 yards with new brass. The load was the typical load I use in F-class, which I normally wouldn’t have used for fire forming, but that’s what I ended up with cause I was loading those anyway and realised I needed more fire formed brass to start another batch. Anyway, that group was .135MoA in a 10 shot string. The overlay of all 50 pieces/shots was tighter than my normal agg from a F-class match by around 1/3. I found this amazing, as the velocity had to be less by 50fps or more. As I said previously, this extreme of accuracy may have been a fluke, but doing all this fire forming and such isn’t necessarily going to make a difference to a hunting rifle if the shelf. It’s up to you what you consider to be ‘enough’ in the race for good ammo. I work up a load in fire formed brass, then load up 100 rounds of new brass and hunt with it to get fired brass, as those rifles are just for hunting, not target shooting doing 100-200 rounds a weekend. Cheers. [/QUOTE]
