Late model M70 Winchester claw extractor Removal

Post by Wm.Traynor » 15 Jan 2025, 7:20 pm

I am close to resizing my cases with a bump die and am going to test the resistance of the bolt to closing with the F P and extractor removed.
Trouble is, I don't know how to remove it. This site and the web has yielded nothing. Not a mention of the claw extractor at all. Plenty about the push feed jobbie but I reckon I could manage that on my own.
Can someone tell me how to get it off as there seems to be quite a bit of resistance to turning, just from the Extractor alone. I am trying to get things so that the bolt handle flops down, on a bumped case.

Mmm., yes if you watch yootube they all say remove fireing pin and extractor.

I've never removed the extractor, only the fireing pin. Suggest the extractor removed does little. But some may think otherwise.

I FLS so that there is the slightest amount of bolt “drag” when the bolt is closed. It’s a feel for it . I use this method on push feed and Mauser type action. With cock on opening the firing pin being in the bolt should make no difference to bolt closing. I back my fls die out progressively in small increments until I feel the slightest resistance to closing the bolt, and that’s it. I get great accuracy using this method. Neck sizing has never worked well for me except on 303 based cartridges. The claw extractor on my FN Mauser doesn’t interfere with this process at all. I hope this post helps. Cheers

Sorry, Wm.Traynor, I don't know how to remove the extractor.
Maybe you would have been better to have simply asked how to remove the extractor - you really didn't need to say why.
Instead, you have received replies that fail to answer the question and, un-helpfully, suggest case preparation methods that are not consistent with your wishes.
Perhaps some knowledgeable person will be along to help, soon.

Yeh, some post just for the sake of posting and complaining. Even when they can't answer the qn.

Never mind oldbloke and No1_49er, I can live with it. Not being able to remove it, is something that I suspected all along when there was nothing on the web. Thank you for your replies, however :) :thumbsup: I will make the best of it and we will see how we go :)

He says he wants to remove the extractor to test chambering, in my reply I’m saying I’ve found it unnecessary. Simple question, simple reply.

I would only remove them if they apply any load to the case, a lot don't. A spring ejector in the bolt face forces the case to one side applying friction to one side of the chamber. A sprung extractor does the same causing friction on the opposite side of the chamber. But some designs of extractor and ejector don't put any pressure against the case so you can ignore them. They may have some friction in the action which might be felt at the bolt handle. I don't see any need to remove the striker in most bolt-action designs. I don't think it takes a lot of time with most actions to be able to feel the difference between normal bolt drag on an empty chamber and drag caused by closing on the case, I don't remove anything, I rely on my own feel of what the case is doing in the chamber.

yeah , same here mate . i usually set up a FLS die to the makers specs then proceed to back out the die in small increments until a dummy round chambers "right ". i put marker pen marks on my die and press as a reference so i can see how far i'm moving the die and go back if i overdo it .then i'll load some live rounds and go test . :thumbsup:

First, on removing the extractor.
I have never owned a M70 Winchester but I do know it has a T slot extractor. They work on the basis of a ball under spring pressure against a ballseat in the base of the extractor. It will have a through hole in the extractor and the ball can be pushed down and the extractor can be manipulated out of it's position by using a suitably sized probe to push down on the ball.
Be careful because the ball will be under considerable spring pressure and can be easily lost.
The ejector will be held in with a pin.
Second, on the wisdom of what you want to do.
Simple answer is don't.
It is far too easy to end up with a dangerous amount of headspace. The only way to achieve zero system headspace is with the use of an accurate and reliable headspace gauge to compare with a fired round loaded to full pressure.
Lastly, where does all this shoulder bump malarkey come from? Is it just an imaginative rebranding of full length sizing or have I been missing out on something for the last 50 years?
