My Bil uses a single shot rifle in 35 whelen for his deer gun. Wife is wanting to get him another rifle for his Christmas. As that caliber is unobtainable for all practical purposes, and I'm not going to load for a gun I can't put my hand on (if I could get brass, he doesn't save, if I had boolits or bullets and primers) I can get 30-06, 308, 6.5 Creedmoor, and would most probably buy a decently nice bolt gun for one of those. I don't deer hunt. Which would you go with for southern white tail? Would only be used with factory ammo....
