300BLK subsonic at .37/round

[Nonliberal]

When it comes to sub loads I do my own..Main reason, I take a 16 inch barrel and a 21 inch barrel and shoot my loads as I am trying different weight projectiles and powders.. It ain't a quick fix, it takes a lot of time and patience to develop a sub round, that will work for a specific length barrel with a certain twist rate. Since they all act different in different configurations...I roll my own...Good luck and thanks for the report..

I shoot all of my loads out of a much shorter barrel but it gets the job done.

And it goes off the rails

It's not the round nose that's causing the tumbling. I shoot the SSA 220 round nose as my SD and hunting round with no problem. That round does seem to be seated very deep in the case, tough. COAL is very short.
