Lee 309-230 load 300 bk

[clearcut]

I'm looking for a load that will cycle my 16" pistol gassed 1:8 AR using IMR4227 and the 230grn. PC'd cast boolit subsonic is not an issue.
Thanks CC

I'd start at 12gr and work up till you get reliable cycling and quit there. Don't take huge steps, 0.25gr increase at a time. Pressures go up quick in a heavy bullet load in the blackout. What someone else has found safe might be over pressure in your gun because of slight differences in load workup or your rifle.

Get Hornady's load book. Lots of 300blk data there.
