Buy an used Kimber Montana 8400 WSM or Kimber Mountain Ascent 8400 WSM donor and #2 contour barrel of your choice and have the action trued & squared and bedded, trigger adjusted to your liking ( I use 2.5lbs) and chambered in your desired cartridge,
Great thing about the Kimber Montana rifles is they are an all SS action, have an excellent adjustable trigger and have CF stock that's easily altered, ie- palm swell, high comb, cheekpiece.
I've had many rifles built on the Montana 84M, 84L and 8400 actions, they are lightweight and always accurate,
84M (SA) 6.5CM, 7mm-08, 6.5-284
84L (LA) 6.5-284, 280AI
8400 (WSM) 6.5 PRC 3 of them
8400 (LA) 300 PRC 2 of them
Hopefully I can use one of the Sherman Cartridges for a build in the near future.
