Is anyone loading for 338 arc yet?

I’ve been reloading subs with maker and cutting edge bullets. Sw blackout powder has been decent. This is in a 1:6 twist 8” ar15.

Mine is a 9 inch 5 twist. What velocities are you seeing?

1030-1050fps. Obviously I’m not pushing it so I can stay subsonic. I believe I am using 12.5gr of SW blackout with the 300gr maker

Awesome thanks! I didn't know if I would be able to get up to 1050 with the short barrel with the makers. Looks like that wont be a problem.
