My Godson shoots the A-Bolt Micro in 260. He is 11 years old and weighs 88 lbs. He shoots factory 120 gr. BT's and has absolutely no problem with the recoil. He has actually made a 250 yard shot on a doe this past youth hunt. I measured the distance with my range finder after the fact. Your wife will have no problem with the Browning and it is the best looking of the bunch you listed. Any of the rifles you listed will work well with the 260.
