I am 73. The recoil doesn't seem to bother me very much yet. The rifle weight sure does. In '06's, I like my M70 FW more than my Standard grade. I like my 84L Montana too but I am noticing the recoil.

I use an '06 more than anything else but I also shoot larger rifles, often a .338 Win Mag. I do notice I don't shoot 50 rounds at a sitting with it much anymore.

In the spring and summer, I used to pack a Remington 660 in .243 or a 6.5 Swede carbine for spring bear or whatever. I switched to a 6.5 Creedmoor in an 84M Hunter a few years ago. Nice rifle. It may become my new deer gun.
It kills like a Swede but much more accurate and a better trajectory.
