Without spending much time developing loads, I was getting right at a 1/2 moa at 100 yds. with 140 grn. Accubonds. Worked well out to 500 yds and never really tried to go beyond that. That was with Winchester brass. About 5 yrs ago I decided to go in a different direction and it really hasn't been shot since. I didn't keep a real accurate count of rounds. I know it's quite a bit less then 400 and probably closer to 300.
