30-06,25-06,.308,270 are allgood choices and will do the job. come crunch time when her heart is pounding she wont notice the recoil. I shoot a 12 gauge marlin 512 slugmaster here in maryland for deer. It kicks like a mule while shooting on the range.But when there's a nice buck in front of me I've never noticed any recoil. Maybe my hearts beating to much to notice any recoil.
