Feeding Problem in Ruger M77

[Mike T]

Hi,

I'm having a problem getting rounds to feed into my Ruger M77 Tang Safety. As the bolt starts pushing a round out of the magazine, the round moves forward, but never goes under the extractor. The round either just pops up out of the magazine or gets pushed into the chamber in front of the extractor, and the bolt won't close.

In the first picture below, the bolt is rotated into the position it would be as it begins to push the round. Note that the round would have to jump the rim of the bolt to get onto the face of the bolt.

In the second picture, the bolt is in the position it would be when the round is in the chamber and the bolt has been rotate down. If this were the orientation the bolt was in when it's pushing the ound forward, the round would slip right up into the bolt face and go under the extractor.

Is the bolt assembled or installed wrong, or am I crazy? No, wait, I AM crazy. What about the bolt?

Thanks for your help,

Mike

Is the ejector free to move?

Feeding Problem

Nicky,

The ejector is stiff, but it does compress.

How do you propose the case rim push the ejector down into the bolt face if it were CRF??

It couldn't push it down, because it would be pushing against the side of it, not the end..

Your rifle is push feed.
And the extractor snaps over the rim when the bolt is closed.

You just ain't cranking on it hard enough!!

The original Ruger M77 design was a push feed with a claw extractor and pin ejector, like yours.

The true CRF action came on the MKII, and used a blade ejector in the left receiver rail.

It had no ejector plunger in the bolt face like your older one.

Note that the round would have to jump the rim of the bolt to get onto the face of the bolt.

Since your rifle is a push feed design it is supposed to work that way. Even with most modern CRF rifles they will jump the rim to allow feeding directly into the chamber.

Why the bolt won't close is another matter, but the extractor appears to be working as designed.
