I owned and deer hunted with a Rem 700 7Mag for many years and killed more than a couple deer with them, they shot great, long or short range, killed a few antelope with them too no problems. I guess I am just lazy and prefer not to get hit with quite as much recoil any more as I have a .280 Rem and a 7-08 (can't escape the 7mms), more and more I find the little 7-08 in my hands during deer season. I have absolutely nothing against any belted magnum from the smallest up to the largest as long as the shooter can handle it safely and well. Were I going Elk hunting or had the opportunity to hunt long range the 300 Win Mag would certainly be a viable option. If you showed up in my deer camp to hunt with a .340 Wthby of course we would razz you some, but before it was over I would be the first in line to shoot it just because. There was a time when the .300 Mags (mostly the older H&H's?) ruled the 1000 yard target range. Beware the man who can cradle his .300 Win Mag or .340 Wthby Mag and place bullets at long range, he is a force to be reckoned with.
