I have a 1-10 22-250 Ai that would not shoot the 80gr Bergers but would shoot the MatchKings , the Bergers had large groups at 200yds and keyholed at 300.
I had to settle for the 75gr Bergers but found the 75gr A-max to shoot he best of the bunch. Your gun may be differant.
If you give Berger a call I'm sure that they'll send you a dozen or so to try.
