I've read of a few problems with the Kimber in feeding.

Why not go with the 375 H&H like you want but choose a more trusted platform like the CZ 550 or Winchester model 70 or Whitworth,or even an older pre 75- 85 Sako.

There's lots on Guns International to chose from. I always thought a Sako Mannlicher Carbine in 375 H&H would be cool.
