I was thinking of buying my wife a light-kicking rifle for target shooting and maybe deer. She has only shot once before and is only 5 foot - one half inch tall and weighs about 115 pounds. I started her out with the .30/06 and it wasn't something she'd really want to shoot again. One rifle I have in mind is the .257 WSSM. I understand that it is ballistically comparable to the .25/06. I have read that it accomplishes .25/06 ballistics with less powder, and therefore, slightly less recoil. If chambered in an 8.5 pound rifle with a 26 inch barrel firing 115 grain bullets, how would recoil compare to that of a 6.5 pound .30/06 with a 22 inch barrel loaded with 168 grain bullets?
