I have a Ruger MK II in 30-06. It is the Mauser clone claw type bolt. It is my understanding that this design was not to ever double feed if you work the bolt fast, slow, upside down etc. This one does double feed with slow working of the bolt with surprising regularity. Is this common? It shoots very accurately with many loads. I really like this rifle as it is the first centerfire rifle I ever bought, years ago. Should I get this fixed? I have heard from a gunsmith that if it shoots great don't mess with it. Opinions?

Hm... 57 looks and no opinions? That is a first for this crowd.

Maybe I should rephrase the question. How is it possible for a CRF MK II to double feed? This is likely never to be a DGR. Is that a big deal have ironed out?

I'm not sure that the very first mkII's where CRF. It seems like I read somewhere (maybe here) that the first ones had the same bolt face as the original m77.

Otherwise it shouldn't be to hard to straighten out a your rifle if it is indeed a crf. Most any competent gunsmith should be able to help.
Like you have already been told though, if it shoots fine what's the big deal. If your like me you probably just want it to work right?

The first MKII were not a true CRF. The first ones did not have the bottom of the bolt open to allow the case to slide under the extractor. Working from memory only I think that it was very minor job to correct this.

yep paul is right..

the original and round tops are pushfeeds, alot like a rem

first of the mkii was, but had enclosed boltface (think wincheter CRPF)

rest were opened up like mausers

There are a lot of MKII's with open bolt face that do not alwalys feed like a CRF.

The failure's usually occur when feeding from the same side, on any particular rifle. Most folks blame it on a OSFA approach to rails, magazines and followers.

and there's a couple rugers that need to be "bumped" to feed push feed.. but i like having a dgr that i can throw a round on top and close the bolt, from the factory...

500gr at 2350 AND all the realibility of a crf, !!

Thanks for the replies. I bought it in 1994 if I remember correctly. This one looks just like my 98 mauser bolt face. I will get my smith to look it over. I do just want it to work right. Good hunting. "D"

I guess the biggest thing is that I have bought into the crf concept and was very disappointed when I figured out that it double fed almost all the time when worked slow. Just what a CRF is supposed to prevent. "D"

What specific way does it double feed? Is it always from one side? Does the round jump from the extractor?

The sure way to make any CRF double feed is to use cartridges that are too short for the magazine. The loaded rounds must fit the magazine front to back. Not too tight of course.

The worst ones are the Mausers chambered for the 7-57 and 8-57 as the bullets were made shorter as things evolved.
