strongest extractor

[351 power]

everything i read says the mauser bolt action extractor is best. would you agree? who is #2 or #3? why?

[Dave in WV]

The true M98 Mauser I would agree is the strongest by design. After that I could only guess.

[jeepmann1948]

I would hazard a guess that the pre- 64 Winchester Model 70 would be as good or at least 2nd in line

[Coyote Hunter]

There is the Mauser style, then there is everything else a distant whatever.  One reason I like Ruger rifles.

[charles p]

It's strong enough when it works every time.  Only extractor problem I've ever had was on semiauto shotguns when the extractors wore out.

[Swampman]

The Mauser/Winchester extractor is strong but accuracy suffers.

[SHOOTALL]

The only problems I have had is with Rem 600's . The rugers I have shot seemed strong also.

[Bigeasy]

The Mauser type is probably the most sure.  The SAKO style extractor is often noted for its grip.  I hear its popular these days to convert the Remington 700 bolt to this extractor.

Which defeats the 3 rings of steel.  They can blow out.

Over kill , Better to be able to reload .

Well Larry, as I remember, "these days" started about the time the 700 was introduced!     And it was/is a popular conversion.  Being a slave to current fads, I often thought of having it done myself until I came to the conclution 20-30 years ago that the 700's extractor was fine and the Sako wasn't any better, just different.  Unfortunately I don't remember the basis for that conclusion since any record of the reasoning (including mental) is long gone!   

But I believe it, just like I believe the M98 style extractor is the strongest!

Yup, Savage leads the way out of the box.

Only Remington has the three rings and have to use that POS extractor to get the three rings of steel. The Remington POS extractor may work but it's still a cheap POS. BTW, I have a Remington and it has the POS extractor. The three rings of steel is marketing hype to cover for the POS extractor. Did I mention Remington uses a POS, cheap stamped steel extractor?  

[Swampman]

Owned many and shot many more.  Never seen one fail in nearly 50 years of using them.  I'm just sayin.

Before this turns into a Ford Vs. Chevy.
All the extractors have a claw that holds onto the rim of the round and pulls it out.
the size and location of the claw changes based on design.  the Mauser, Ruger, Winchester, Springfield being the largest and there for grabs the most of the rim.
I have to say I forget what the Savage claw looks like and ho much it graps but it is a puch feed and will have a smaller claw like the remington or the Sako.
I am sure someone here will be able to tell you advangages over one or the other nad disadvantages.  "the large claw will pull the back of the case off or the snap claws are prone to sticking and not give reliable extraction and you had better carry a ram rod with you."  What ever someone gives as an argument others will give similar ones back at the others design.
You stumbled into the who builds the best 4X4? Question of the bolt action world. 
Are you looking to build a dangerous game rifle?  only real reason you would want the strongest extraction, making sure the fired round is out of the reach and ready to accept the life saving next round from the magizine.
As for bolt action designs, I own CZ, Enfield, Mauser, Remington, Ruger, Sako, and Winchester (did it alphabeticly so as not to hurt anyones feelings)  All will feed all will extract and I would not think twice about taking any of them after Dangerous game in the right caliber.  Some how the CZ in 223 does not seem like a DG rifle.

[Dave in WV]

The idea of how the CRF design makes a rifle more reliable is IF it is working properly the bolt/extractor grabs the cartridge when the cartridge is stripped from the magazine and won't allow another cartridge to be stripped from the magazine until the case is ejected. The idea is to prevent double feeds. When my son shot his first deer I watched him as he chamberd a cartridge after the first shot and he 1: didn't turn the bolt handle down, and 2: pulled the bolt back and stripped another cartridge from the magazine creating a jam/double feed.

If the firearm is working properly and used properly they will all work fine.

[charles p]

You brought back a funny memory.  For my son's first deer kill, he was sitting in a box stand in my lap.  I eased him onto his feet and picked up my rife to "back him up".  I knew he would need it.  The clear cut beneath us was full of doe deer.  I watched to see which deer he was aiming at and I aimed at the same deer.  He fired, missed, and I killed the deer.  When he shot, he shucked a 243 from his Mod 70 and when I fired he shucked a live load from his rifle.  He wanted to shoot another deer, so I let him shoot again.  We repeated the process and again he shucked out his spent round and alive round after I fired. 

I think he had "doe fever".  The next day he killed a running buck on his own.  Was not that deer's lucky day.

LOL,
You must have told him to reload after every shot.  Need to change that to reload after you shoot.

I have a Ruger .308 SS and it hits a dime at 100 yards with Hornady 150 grain light magnum bullets from a bench rest.  I also have a pre-64 Mauser 30-06 and it colverleafs with 150 gr Remington Core Lok bullets.  Barrel is floated and glass bedded.  I like the claw for extraction and it can be taken down without special tools to clean the spring and firing pin.

[Reverend Recoil]

The French MAS-36 rifle has a very good extractor.  It rotates with the bolt but I don't see that as a negative.  It is strong, simple, and allows controled feeding.  Modern rifle designers would do well to copy it.  I have never had any trouble with the extractor on my M1 or AR15.

I've posted sub-caliber 3-shot groups from more than one of my Rugers, no need to do so again.

An Interarms Mauser action was the basis for a custom 6.5-06AI that I use to shoot clay pigeons at 600 yards. 

It may be that in a target rifle the Mauser extractor is a theoretical disadvantage.  In hunting rifles it doesn't make a whit of difference.

[myarmor]

If you pick up a Ruger you can plainly see it's almost identical to the Mauser design and is very effective. I wouldn't down it.
But if the military depends on a Remington 700 action for almost all of there sniper rifles for how many years now?...and up to this day... I am very comfortable using a 700 for any of my hunting applictions and have never had a problem with their actions, not to mention it's the most popular action to build a bench rest rifle on as far as factory actions are concerned. Though I have to give it to Savage with their new offerings, they are pretty impressive.

[351 power]

appreciate all the comments. and hunting accuracy is not a problem with any type of extractor i think. concensus seems to be mauser and then all the rest in the extractor area of discussion

[Dave in WV]

The reason Remington 700 style actions are used for sniper rifles and bench rest rifles is the round action is suposed to be easier and cheaper to get to shoot well.  They are used so much in those applications may bear it out. Can anyone confirm the stamped steel extractor is used on US military sniper rifles?

Depends on what generation Ruger.
My older M77's are a push feed with a claw extractor and a plunger.  Kind of like a Remington 700 mated with a Mauser.
From what I have seen the new M77 II is a mauser design and uses controlled round feeding.

[JPShelton]

Here's one for Swampman.......

I have vague adolescent memories of an ad Big Green ran way back when.  They used a "cartridge case" specially made to have an extractor groove at both ends.  A Remington M-700 bolt was hooked up to one end. A Mauser was hooked up to the other.  This was done on a fixture that allowed the bolts to engage in a "tug of war" with the cartridge case.

The Remington M-700 was the winner of the duel.  While the Mauser held on to the "cartridge," the Remington pulled the head right off of it!

It might look like a cheap piece of stamped metal, but the Remington M-700 is plenty strong.

see i was thinking that the sako type, or the ones like on the mini 14 might be stronger. mainly because they have a larger size/surface area contact

[SHOOTALL]

One could not know the construction of the speical case nor wheather the larger area of the mauser  would spread the force in a way that didn't cause splitting . Better to make a fixture out of solid steel and apply pressure until one breaks then and only then would we know which of those two were strongest . At best all we know from the double ended test is which end of the case was weakest .

True enough.  It was an ADVERTISEMENT, after all.

That said, when you look at how the extractor on the M-700 works, it gets plenty of purchase on a case.  While I don't have a lot of love for the Remington M-700, I think Remington's M-700 extractor is cool bit of engineering genius.  I also think that M-16 style extractor conversions for M-700's primarily exist to divorce those who really don't understand how something that looks so fragile as a component part can be "hell-for-strong" once properly and correctly installed.  From an engineering standpoint, it would seem to me that an M-16 style extractor retrofitted to an M-700 would be a retrograde step, rather than an "improvement."

[ourway77]

I agree I have replaced several Remington 700's with Sako extractors. Lou

[Dave in WV]

Remington strenghtend the stamped extractor with a non-rivited one. The rivited type tends to break more often at the rivit.
