"If you could find something in .260 it would be even better."
I'm inclined to agree with that statement. I'm one of those who feel the .243 just might be a tad too light for deer. I know many here have had great success with the round, but that's my opinion and I'm sticking to it.
Many years ago I owned a 6.5x54 Mannlicher-Schoenaur that sadly some low life stole from my truck in Elko Nevada. Using the 140 gr. Norma load, that little rifle was a deer slayer supreme. It's been well over 35 years since that rifle disappeared and I miss it still. The .260 Rem. and the 6,5x55 are pretty much the same thinf regarding power and recoil. Very pleasant. Another very pleasant cartridge to shoot is the 7x57 Mauser. The 7-08 Remington is really just a modern version of the 7x57 in a short action rifle. The 7x57 has less recoil that the 7-08 because of the early rifles chambered to 7x57 being considered too weak to handle modern pressures. All factory ammo is downloaded to accomodate those weaker guns, thus handicapping a fine cartridge. No matter, a factory 140 gr. load is more than adequate for White tail deer. My preference is for Winchester's 140 gr. loading which unfortunately is only made on a "seasonal" basis. Remington's 140 gr. is also a good one but probably the easiest to find would be Federal's 140 gr. load. I haven't used that one yet and probably never will as I use Winchester brass and handload all my hunting ammo. I do not like the Federal 175 gr. load and it cost me one if the only two deer I have lost in well over 50 years of hunting deer. Let's just leave it at the velocity didn't come close to advertised specs and let it go at that.
All I can say is if you can locate a Winchester M70 Featherweight (earlier push feed is fine as that is what I have.) in .260 Rem. or preferably 7x57 mauser, shoot strictly factory level loads in the gun and if recoil is still a bit much, just have a gunsmith install a Pachmeyr Decelerator pad on the gun and hunt happily ever after.


Seriously, you could do the same thing with the 7-08 and ammo would be a bit easier to find. If you handload,I've been hearong some very good things about the Nosler 120 gr. ballistic Tip in the 7x57 and 7-08. According to folks over on the Nosler forum, that 120 gr. bullet is made using the same jacket as the 140 gr. bullet making it a pretty strong bullet that does not act like a varmint slug. A full power load with that one would have some pretty light recoil. I have been shooting some 120 gr. Barnes TSX loads in my M70 and recoil is quite close to my .243 M70.
Just the way I would go if I were in your situation.
I'm considering getting rid of my hardest kicking rifles because I'm well past middle age (Be 75 come the middle of next month.) and the arthritis in my right shoulder doth protest mightily when I shoot the big boomer. (.338 win. Mag. on up. Way up.)
The 7x57 shoots a 140 gr. bullet around 2600 FPS and I believe the 7-08 around 2800 FPS. A handloaded 7-8 at 2600 FPS would be more than adequate for your needs should factory level loads be a bit too much.
