Does anyone have this one, and have had success in AR-15 .300 blackout?

It was designed for the M-1 Carbine, so it should work. I must admit I’m a near virgin with loading 300 BO, so don’t lean too heavily on my speculation. ;)

Do you happen to have that mold?

[Green Frog]

I had it years ago to use with a 32-20 low wall I was shooting. Unfortunately, both are now long gone. :(

I believe that 311410 (130grs) was designed for .30 Carabine and MP 312-159 Hunting was new design by Bobby Kell Jr aka “Boolitdesigner” for MP.

Maybe my eyes are fooling me but those are some serious looking gas checks on those boolits. Reminds me of the "son of a half jacket."
