Thanks for all the good comments. Rifle is AI AX. Twist is 8. Bartlein blank used, by AI. Don't have reamer print or spec.
Factory 136 scenars: CBTO 2.089; don't touch lands, good groups.
Facroty 123 scenars: CBTO 2.136; touch lands; don't shoot as well as 136.
Plan on 140 hydrids first with the fireformed brass.
