Out to 600 yards you can do the fast and flat rifles like the 257 wby. Mine shoots the 100 grain Barnes at 3780 fps and is incredibly flat out to 600 yards but then falls off the table. Others are similar. This is about as much as you can get and stay in a fairly light recoil rifle. I agree with some of the other guys that you do not need a huge magnum with a lot of kick or requiring a muzzle brake
. I just took a nice caribou with this load last week at 486 yards. Took two steps and fell over.
Just suit your rifle to your hunting style. If you do not need to go beyond 600 yards you do not need a super magnum with heavy hard kicking high BC bullets. A lightweight flat shooting bullet in the 3600-3800 fps range will work just fine and get your point blank range way out there. Something like the 264 win mag or 7mm rem mag with light bullets (120 grains) doesn't kick all that hard and will put you super flat out to 600and wallop deer size stuff.
