I'm building up a budget 284 now, hopefully it will shoot the mile well and maybe 2,000 yards if I'm really lucky. I have another action that can take CIP length magazines. I was initially thinking of building it as a better 284 but reading about 300 PRC it got me thinking and then I started to wonder if there is a similar chambering that is less overbore by using a .338 bullet? It seems like 300 PRC might have brass issues and one person went as far as fire forming RWS 8x68 brass to do better. Does 338 Edge have good parent brass? Will either of these take me out to 2,500 yards with half decent hit probability? Is there anything else I should look at? I might fall back to my 284 plan but just want to know if going bigger can significantly extend the reach.
