How much practice will you do with a 300 Win Mag compared to a 308? 308 168gr loads are supersonic to 850+ yards. Plenty for deer at 600.

I'd pick the one you'll practice with the most. You'll need a LOT of practice to reliably hit a deer at 600 yards from a shooting house or stand.

If you want to go big, then put your big boy pants on all the way and go 338 Lapua.
