I have one hole groups at 100 yards and 5" patterns at 200.
Model 12 in 22-250 Rem.
52 gr SMK.
Vihtavuori N135 powder.
33.1 gr.
BR2 CCI primers.
Winchester brass.
I have messed with all the suspects.
Changed stocks, floated the barrel and the tang.
Scope is tested and tight.
Parallax is correct.
Crown is fine and bore looks good.
Different shooters.
Different seating depths.
1-12 factory twist barrel.
EVERYTHING I try gives roughly the same result.
Do I need lighter bullets to stabilize at longer ranges ?
