I'm wanting to rebarrel a RPR from 556 to 300 blackout.

I would like to throat for the NOE 311-222-RN. This will really limit what I can run for this barrel. The twist will be 1/10.

Green hill forumal shows it to be stable at subsonic velocities.

Any one running this bullet in a 30-06 or any gun in 1/10 twist with light loads?

I am not interested in a 1/8 twist.
