Winchester model 70 claw extractor operation

[misterfinch]

So my question is in regards to the operation of the claw extractor on the Winchester model 70 current production. When is the claw extractor supposed to grab ahold of the cartridge? Is it directly out of the magazine, or is it a gradual process as it enters the chamber?

When slowly riding the bolt forward it sometimes has full control and other times it doesn't. Rifle is brand new chambered in .308 (super grade).

Thanks for the help...

The cartridge should go up behind the extractor as the bolt goes forward. The magazine spring is pushing up on the cartridge so within the first 1/2" (or so) of travel the cartridge rim should be pushed up behind the extractor. Different cartridges push up at different rates depending on the length of the cartridge in the action and where the magazine block is but when the cartridge gets to the full horizontal position it will be behind the extractor.

Thank you for your response Fjold. What you described makes sense. Just not in my case. At least not consistently... i found more info on their site...

It is called controlled feed when the rim is fed up behind the extractor, as opposed to push feed in which the extractor snaps over the rim as it is fed. My Ruger 77 first model looks like it has a controlled feed extractor but does not, the second version does have controlled feed. The Mauser's invented it.

And the Springfields licensed it.

That's interesting. I didn't know that Winchester was doing controlled feed in any of the contemporary rifles. My Winchester Model 54 has controlled feed. But it's really about half-Mauser in design.

Great explanation in the video. After many calls to Winchester they believe the rifle may have a timing issue or some other problem... I'm going to be sending it in to hopefully get the problem resolved. I'll probably record a short video and post it to show the issue and a follow up after it's resolved (hopefully).

Thanks again for the help everyone.

The "Classic action" with controlled round feed was introduced in 1992
