Its defiantly an issue with the two Ruger No. 1's I own, one is a International full stock in 30-06, and the other is a Tropical Stainless in 375H&H, I've fixed the International by beveling the front of the safety (no pictures to show, sorry) But I haven't fixed the 375 as of yet, should be an easier fix because its stainless (?).

Lots of people prefer the shell to hit the safety so they can save the casing, I reload, so thats a valid point, however, you can tune the ejector into an extractor, that will do the same thing. Its a design flaw, and the only part of the Ruger No.1 I don't like, the rifle otherwise handles smoothly, balances great, and both mine are great shooters.

***Note, the CUSTOM inletted safety is not mine, but I thought I would post the picture as its a great example of how the safety SHOULD have been from Ruger***

Heres some pictures that illustrate the issue (Snap cap in place of real shell because its easier to see)

Hope these help.
