Hey guys,
I’ve searched all over this board and googled the heck out of this mold, and got a lot of mixed responses. Thinking about getting into casting for the 300 BLK, specifically heavy (220 gr+) bullets for subsonic use. I’m trying to get some opinions from the experienced casters on here as to their thoughts on the Lee/Midway mold. It seems like a cost-effective alternative to some of the better-accepted, and significantly more expensive, NOE and Accurate molds. Trying to keep costs down, since I don’t know if I’ll enjoy casting or not, hence the appeal of the Lee/Midway mold. The rifle I’m interested in shooting through is a 8.5” 1:7 twist SBR with a Silencerco Hybrid can. I plan on powdercoating and not lubing. It’s just a plinking gun for fun, so high accuracy is not at the top of my list. I’d be happy with a 3” group at 25 yards.
I guess my main concern revolves around bullet stabilization. The biggest complaint I’ve seen with this mold is that it drops small and the bullet ends up keyholing through paper at short distances. Keyholing out of a regular barrel is not so much a concern, but baffle-striking the suppressor with an unstable projectile is.
So, anyone have any opinions on the matter?
Thanks in advance!
