I purchased that ammo through Hornady. It will not cycle in my mini 30. 1 in 10 twist, I guess I will be running supersonic in this rifle using these.

Anyone hand loading subsonic Hornady 255gr Sub-X’s in their 7.62x39’s yet?

Might try bumping your loads up until they go supersonic. If they still go sideways, yeah you're prob not gonna have enough twist with that heavy long bullet. If it shoots ok, drop your charges until just barely subsonic.

Some guys a few years ago were playing with a "7.62x39 Jackhammer ", AK round with a faster twist for heavy/or subsonic. Mostly in the AR platform. I have a AR barrel here in 1-8" twist. Just got sidetracked on other projects. I wanted to try one in a bolt action, savage barrel shank, but then AK ammo went through the roof. Not cheap anymore.
What twist rate?

Dang. I am going to try them in a couple 1:10 barrels and see how they turn out...
These would cycle in my rifle and were fairly accurate. I just really got it sighted in and went out to 200 yards will have to check velocity and accuracy next time. 1 in 8 twist.
Velocity on the box listed at 1060.
