I'm considering a .458, .450, or .50B AR upper for deer and hogs. Leaning towards the .450 bushy.

What's your take on heavy bore AR's for big game hunting? I'm leaning towards the .450 Bushy mostly for the MV/energy, but I'm open to hear opinions on other heavy bores. Maybe there's some political or other consideration that I've overlooked?

Sometimes I worry that I have split-personality disorder, because there's part of me that is giddy over a bullets with BC's over .45 running over 3300fps, but then there's the other side of me that loves a big fat pumpkin trucking along south of Mach 2.

I was planning to rebarrel my 6.8 to a grendel, now that things are ironed out with the licensing, but have since decided to go with a .243WSSM, and will be buying a DTI receiver, so my CURRENT 6.8 receiver needs a job...

Which is where the .450 bushy comes in. It MAY defeat the purpose of the AR platform, since both the .450 and the .243 are 5 shot propositions, but at least they'll be comfortable and fast firing.
