sub-sonic 30-06?
I have boxes of 240gr boattail jacketed HP bullets in 30 cal. Are there safe loads with Unique powder to get near sub-sonic velocities? If so, is a filler required to keep the powder contained?
I shoot these bullets in a .300 Whisper (now called Blackout) at sub-sonic and would like to try them in the '06. Thanks in advance.
