Can't help mines 1-12. I just flipped through my books/data and Barnes is the only one that say's "1-9 or faster required to stabilize,,," some of their longer bullets. I'd think you'll be close if you use AR data with it's 1-7 ??
IMHO just because the 1-9 will stabilize longer heavier bullets don't mean it won't stabilize short light ones. Guess you'll just hafta experiment, that's the fun of hand loading

, someones pet load may not work as well in yours.
Pick a bullet and go for it, if I was you I'd start with one 50-55 grns. Kinda thought about a 1-9, I could shoot the big heavies and maybe try large game, but I have other guns for that and my gut tell's me to use something bigger anyways.
