    NOE-310-225 super sonic??

    I just bought one of these molds to use with a 10 1/2 inch A.R. pistol with a 1/8 twist does anybody have any sort of low data for a super sonic 300 blackout I would like to try to get it to shoot about 1300 to 1400 ft./s is that even possible

    Since you’re not constrained by 1050-1075 threshold it should be easy to find an accurate load with H110 or similar powders.

    You will not make it past 1100 FPS with that heavy of a bullet in a 10.5” barrel. Try a 150gr or less bullet.
