What will the barrel be chambered in?
My guess is that the 130's will do just fine.
You won't know until you try.

It's a 1-8.5 and so far it's shooting the 139 scenars fine. But then again it's still warm out. If the twist was border line I wouldn't think that I would have issues unless it's cold.

I shot 130 accubonds in a 10 twist under 1/2 moa consistently. Don't give up on the 140 bergers until you try seating them INTO the lands up to .020." I have a 6.5 sherman with an 8 twist and they won't stay under an inch unless I seat them .020 into the lands and then they shoot 1/2" or better......Rich
