I was thinking about getting a Nosler TGR in 300 WinMag, adding a muzzle break to it and learn to deal with the recoil when I read an article yesterday about the 7mm Rem Mag. Apparently it has about 25% less kick than the 300 winmag and still does the same job. That job being taking down elk and moose with ease at long distances 500 yds plus...Does anyone have any experience with this cartridge? Also most importantly, how easy is it to get the round? With things being the way it is today, one can only expect tighter restrictions on ammo in due time...so it is better to just stick with the rounds that are popular now and hope after the looming apocalyptical restrictions we can still get that ammo...any insight on this will be much appriciated.
