I'm thinking about a big bore AR but don't know much about them. I'd most likely cast my own bullets so the expense of bullets is not a factor for me. Also, are all three proprietary brass? I'd like to be able to make my brass from existing stock - like the 300blk is made from .556.
Well, that's my thoughts so far. Any of you with knowledge on this and/or experience, it would be great if you'd share.
Thanks
