My PH just wrote me and asked if I could bring him a Leupold QR bases and rings to Dallas for him.

Question is, do all 375 H&H pre 64's have.435 hole spacing? Or are there some .330 spacings out there?

Some are not even drilled and tapped; some have been done after; some different. Bring a set of both, it won't break the bank.

terry, all of the pre-64 modle 70 actions that left the facrory drilled and tapped are.435. The post 64 H&H mag length actions have the .330 spacing.

Thanks, the info I needed.
