I have rifles in all three calibers. My wife shoots them mostly. She says the 7mm-08, with 140 gr bulletsrecoils less than the 260 Rem with 140 gr bullets. And of course we're getting faster velocity out of the 7mm-08.However, our favorite load in the 260 is Sierra 120 grPro Hunter @ 2875 fps, and we both say it recoils the least of all. She's killed a lot of deer with that rifle and load.
I would prefer her to hunt with the 308 with a Barnes 130 grTSX @3000 fps, (recoils about like the 7mm-08 w/140's)but she thinks her 260 is magic and won't use anything else on deer. Go girl!
