3 for anything and everything:
1. Stainless 77/22 in .22 WMR. It will do everything .22LR will and more. The reverse is not true.
2. Stainless tang safety M77 in .30-06. The reasoning there should be obvious.
3. Stainless 700 in .375 H&H. For anything that the .30-06 is a little light in the loafers for comfort on. You know, brown bears and cape buffalo and the like.
Its all downhill from here. Except the parts that are uphill.
