Kute,
Yes. I had a Ruger Alaskan that feed extremely well, although I believe the NP3 I had the bolt coated with was a contributing factor.
Stocked it in a McMillan and it was a nice rifle. However, it only held three down and I simply didn't like the Ruger safety. Since it wouldn't be replacing my .375 H&H's, down the road it went.
Recently picked up a CRF SS M70 .375 H&H action, so next year I'll be building yet another!
