I did run some .416 ruger rounds through some of my magnum bolt face rugers. Some are CRF with no lip on the bottom of the bolt and some are push feed.
The .338 without a lip on the bolt face fed smoothest and seemed to control the round as it should. The others seemed to work ok also and likely wouldn’t need much work. I suppose the lip could be machined off also to make them CRF?
With the price of Ruger Alaskans right now this is one of the rare times a custom may make economic sense if you can find a reasonably priced donor. A stainless model 70 in .416 Ruger would be hard to beat for a using rifle.
Yes,
The early M77 MkII that has the lip on the bottom
of the boltface,
the "weak sister" lip.
That lip can be machined off to turn the pushfeed into CRF.
When I was living in Eagle River, AK, in the early 1990s
a gunsmith named Kelly Olson did one for me.
Flawless, on a .338 WinMag.
