Model 70 extractor problems

[M70375!]

Just got a model 70 458 win push feed, wondering if anyone has ever had an extractor fail in these rifles

I have no personal experience with them.
But, Finn Aagaard stated that he had "personally experienced extraction failures with three different post-'64 Model 70 Winchesters, two of them being.458s.
The Model 70 extractors quit due to dust and crud accumulating unseen under them, but a Mauser extractor would have continued functioning despite that."

Finn Aagaard was correct. I have personally seen two post '64 Winchester Model 70 rifles experience extraction failure. One in .375 Holland & Holland Magnum in the Zambezi Valley. One in .458 Winchester Magnum in the Kalahari.

On both occasions, the ammunition used was Winchester Super Speed factory loads.

If I were you, I'd seriously consider having the rifle fitted with an M16 extractor for added reliability. McBride's Gun Works did this for my Remington Model 700 Kevlar Stock Custom in .375 Holland & Holland Magnum.

Thanks for the feedback, maybe I should sell it and get a CRF

My personal opinion, is the true Mauser extraction system, where you cannot jump the extractor over the rim of a cartridge in the chamber, has to be the most positive. As most people state, barring an extractor breakage, that brass or a piece of it is coming out, even if you have to use your foot on the bolt. Though, I have had no issue with the slightly modified, that allow you to close the bolt on a chambered round.

The flip side, I have use my foot on M1A rifles a couple of times to extract unfired rounds. The rounds removed on first stomp, which would not budge when using the hand method. But, those were unfired. Although, it apparently worked on the M14 on fired rounds also.

Bolt guns, I prefer the long claw extractors and fixed blade ejectors. Just seems like a simpler more hardy system.
