300 BLACKOUT tell me about your loads

NOE mold - TL310-225-RN-CE3 4 cavity PB Brass - 225gr sub.



Have loaded some, haven't shot them yet.

I test fired some 195gr SNS blackout bullets over 4.5 grains of red dot, COAL 2.125" and got great accuracy -- holes touching at 50yds with an occasional flier. I think the bullet was lightly contacting the rifling when the bolt was closed due to a bit of force needed to close the bolt, so I'll probably back off to 2.100".

I need to get the chronograph out and see what the velocity is. I believe they are subsonic, but it's hard to tell with hearing protection on.

Has anyone had any experience will Hunters-Supply 238gr lead in an AR platform?

Has anyone ever used Unique and a 165 grain cast bullet?.

[colonelhogan44]

No, but the reaming of the brass to accomodate the 0.311" diameter sounds like a hassle -- there are plenty of 0.309 bullets out there in that weight range.

Hunters-Supply, I bought 500 of them several years ago, just figured it was time to use what I have.

[colonelhogan44]

In that case, load away! I bet you could get away without neck turning.

I've used Unique with a 200 grain 312299 bullet in a Ruger American Ranch. 5 grains was just under 1,000 FPS and 6 was just over 1,000 FPS. SD was 12 FPS which should mean the load wasn't on the edge of being wild pressure swings. I've shot 5.5 grains and it also worked well and should be right around 1,050.

While not the same as a 165 grain bullet, it's at least a reference point.

Thanks, the only cast bullet load data I have been able to find was in Lyman manual #50.
