When I was young I got myself a 7mm Rem Mag then loaded a 300 Win Mag for a friend and then a coupole 338 Win Mags. Recoil bothered me a great deal but I stuck with them and found I could overcome the recoil. Well if I went a month or so not shooting them I was right back to zero. That was pretty much it. Over a few years I got rid of them. Then I got an older Rem 700 in 30-06, it recoiled as bad as the mags did and it went down the road. Never had another 30-06 for years. Today my elk rifle is a custom 1903 30-06. I shoot 180gr bullet's in it and recoil is more than any 308 ever was but very manageable. I found over the years that the smaller cartridge's worked just as well as the larger cartridges.And, within the ranges I'm willing to shoot game work very well! I'm sure there are those that really believe they need a mag and if it works for them, it works!
A lot of people coming out west think they need a magnum to handle elk and shoot long range out here. I've lived out here most my life and in my experience they couldn't be more wrong. As a result I never suggest any magnum for anything to any one. Simply not needed!
