I have a ‘89 win 70 in 375 that is a push feed. Has anyone here upgraded their extractors to the M16 style?
I see LRI can do the upgrade but was looking for feedback from people who’ve had it done. Never paid any attention to the extractor when hunting in North America with her, but something about African game makes me look at that tiny blade!
 
LRI does great work so feel at ease if you choose them. They've done quite a bit of work for me.

No comment on this specific modification though.
 
I met a fellow in Moz last year that seemed very happy with the M16 style that he’d had installed on his M700, but was looking for real experience on the m70.
 
Reach out to Ty @MOA rifles. They likely can do it for you. They are in Oregon.

This is based on a REM 700.

I’m not following the reasoning to change a Win 70 PF extractor to an M 16 style extractor. Common to do that on a Rem 700 which has the notorious nub extractor but not for the M 70 PF which already has an extractor similar to the M 16 style. It will not change an M 70 PF into a CRF anyway. ;)

Additionally, doing that to either the Rem M 700 or the Win M 70 runs the risk of raising the case ejection angle which may cause the unacceptable condition where the case hits the mount, scope tube or scope turret upon ejection. No matter, knock yourself out with whatever you want to do. IMO, it wouldn’t be an upgrade on a M 70 at all and may cause the other issue as described.

458,
That’s the reason I’m asking guys like you who are more experienced to get the pros and cons. I assumed the M16 was considerably more stout than the PF M70 extractor. If I’m wrong, than it doesn’t make any sense at all.
 
The ejection plunger operates opposite to and in conjunction with the extractor. The geometry between the two determines angle of case ejection. If the location of the Win M 70 extractor is changed from center of the lug to the bolt barrel adjacent to the lug, it will certainly change angle of ejection. Obviously no issue for rifles without scopes. Many Rem M 700 (and 721,2) owners who have had the M16 style extractor job done have had to deal with the higher angle of ejection where ejected cases hit the mount, scope tube or turret (or turret cover). The same would apply to the Win M70. Just be aware of the potential.

Got it, thanks. Is the M16 extractor considerably more stout and does it provide a better grip on the case rim than the standard M70 (in your opinion)?
Thanks for the explanation of ejector /extractor geometry, makes sense to me.

A Sako or M16 style extractor doesn’t have any more purchase on a cartridge rim than a Win M 70 PF extractor does. The Sako or M 16 extractor part itself may be a little more robust but it’s extremely uncommon for a factory Win 70 PF extractor to break or fail anyway. The highest percentage point of failure of all these extractors, Sako, M 16 and Win 70 PF, are the small captive springs that actuate them and/or accumulation of crud.

I completely agree…

The M16 extractor modification makes perfect sense on a Rem 700, 721, 600 or 660… they all have the same flimsy design that’s well known for breakage..

Most modern Rem700 pattern rifles like the Christensen come from the factory with an M16 extractor these days..

But I see no reason to spend the money to do the mod to a PF 70.. they don’t have the same failure / breakage problem that the 700 does.. if anything they have a pretty solid reputation for working well and properly… they just aren’t CRF..
 
And those two answers, 458 and midwest, are exactly why I asked. Thanks for taking the time to respond and thusly save me time and money. I appreciate it.

Hello,
I might be able to help you out depending on how many you need. I could probably spare 50-75 .285g A-Frames. They are factory pulls that look like new. Let me know if you are still looking,
Thanks,
Gary
