I also use these rings on a .375 H&H caliber Weatherby Weathermark. Have worked fine for a couple of years.

I do not know if Talley supplies their rings in bases in the configuration to fit your rifle...but if they do I would suggest you give them a look. I was so impressed with them I have switched out 15 rifles this year to Talley stuff from 22-250 to 458 Lott and including a 375 H&H.

Good luck...jjs

I have some on a Whitworth .375, work fine.

Upon checking on the price difference I think I will just give Talley a call.
