Okay. I'm going to buy the forming trim die and try my hand at these. When I get a batch done hopefully someone who has a 300 aac or variant gun can finish loading them and see how they turn out. Sounds like a fun klittle project
If I get my upper put together, I will volunteer for that job. I'd be happy to pay you for the brass as well. If everything comes out kosher, I would be interested in purchasing brass from you if thats something you are looking to do.
Just bought a new revolver so my plans for the 300AAC have been postponed. Shouldnt be too much longer, however, as its basically standard 556/.223 receiver and bolt. I may end up just canabalizing one of my other uppers.
