    50BMG is the biggest.

    my preference is for the 458 socom for hunting its on the same level as a 45-70. second would be the 6.8 or 300blk.

    here is mine in a couple different configs:

    I was going to go with the 40 mm but it might make me look like i'm compensating for something so i went with the .458

    Don't forget the 450 Bushmaster. It'll kill anything up to and including the big bears out to 200 yards and beyond. People say it uses handgun bullets only but that ain't true. The factory Hornadys use the FTX bullet which is a rifle bullet and there are others. This is a great round and hand loading for it is a breeze. Factory ammo is way cheaper and easer to get than the 458 or 50 also.
    The 308 will not work on the AR15 platform, you have to move up to the AR10. I don't know much about the 300 Blackout, you'll have to Google that.
