A while back, Mike Treen sent me a batch of his cast bullets to try - some very nicely cast Lyman 3118! This bullet is typically used in .32-20, and Mike suggested I try them in 300 AAC Blackout. I've finally done something with a portion of the bullets...
Last Fall, the powder coated plain base NOE 314-162-FN cast bullet showed promise in my 1891 Argentine Cavalry Carbine.
I prepared more bullets to try in the 1891 Argentine Engineer Carbine, along with a small batch of powder coated Lyman 311291 cast bullets.

A quick V/R to westcovinadodge - it appears that 17.0 grains of Alliant 2400 is on the edge!
