Mine is a KIMBER Montana 8400 300 WSM
I call it the Old Man, Weighs around 7 1/4 lb. with nylon sling, Leopold 2X8 and 4 shells.
This rifle likes 180 gr. Jacket-Core bullets. Sierra best, then Hornady and Nosler Part. and IMR 4350 powder, 1"and less. Shoots 150 Gr. 165 Jacket-Cole
bullets 1 1/4" 1 1/2 " groups at 100 yds.
Last fall I tried 165 gr. Hornady GMX and the New 168 gr. Nosler E-Tip, this rifle does not like them, 2" groups, Not enough twist to stabilize these longer bullets.
The old style 168 Gr. Nosler E-Tip shot well in this rifle. Less than 1". No Longer Available.
Mauser Extractor, Win. Model 3 position safety, Sako adj. firing pin . Stock design by Melvin Forbes of NULA fame all in one package.
When hunting in rain, I like the bolt construction. Just put the safety on the middle position, Remove from rifle, Twist the bolt handle hard enough to over ride the pop it ball. Unscrew the firing assembly, clean, dry and oil re-assemble. Great for Caribou or Moose hunting in the far north.
I have heard stories about some Kimber Rifles accuracy, The choice is yours.
Good Luck on your choice.
