A buddy and I are looking into a big bore for deer hunting. He is looking at building one for Indiana hunting. I already have a 300 blkout and a Grendel. We was thinking 450 bushmaster, 458 socom, or 50 beowulf. I am a reloader, I reload for all my rifles and pistols and know components are hard to find right now. Was wondering the good, bad, and ugly of the three. We won't be shooting it past 200yrds either. Thanks for any recommendations and advice!
