In the 1970's I grew up on a 30-30 Winchester and I was a little thin guy myself. Kicks wasn't that bad.
hard to beat a .243 or a .25-06 for all around gun in OklahomaMy vote is 243. That is the caliber both of my daughters used. My second choice is 300 blackout.
I own one in 762x39. GREAT rifle and accurateI’ve recent purchased a Howa mini-action in 7.62x39. I haven’t fired it yet (and never have an Howa), but it seems to be a quality rifle and I bet recoil would be manageable while being adequate for deer. I’ve hunted mainly with a .270 since I was in high school, recoil seems about the same as .30-06 to me.
