Hi

I am planning to have a Remington 700 bolt open to magnum bolt face size and by the way i would like to have an M -16 extractor installed

If you know a good Gunsmith who can do that , i 'll appreciate the reference.

And if you have experience to share with a similar modification and Got some advise , i would be glad to hear

Regards

Syl
 
My advice, don't mod the extractor, you would be defeating one of the best features of the 700 design, gas containment. It's not worth it, the 700 extractors work fine as is.

I have one Rem 700 left with a Sako extractor installed. Works fine, never had any issues whatsoever with it. Its a 340 Wby with a RKS gain twist barrel. Accurate and powerful, really a great elk and moose rifle. - dan
 
I honestly don't understand why people want to change out the extractor on Rem 700 bolts.

I've never had one fail, over literally hundreds of thousands rounds fired.

IMHO, if you're having issues with a Remington not extracting, first time, every time, you have another issue with your rifle.

I've only seen one broken extractor on a Rem 700 and that was caused by a nasty reload, which Kaboomed the rifle.

Save your money and put it into a decent optic

However, if it just turns your crank, go right on ahead.

You don't want to give out a location so recommending a smith nearby is impossible
 
power73wagon - You have a bolt with .30-06 sized boltface, and wish to have it opened for belted magnum sized cartridges?
Obviously, this alteration will require a new extractor.
I am unaware of anyone who will open a boltface and machine it to accept a Remington factory extractor, either rivet or clip in.
That leaves the option of either a Sako or M-16 style extractor retro-fit. This will compromise the safety breeching built into the 700. If you have it done, and should you ever have a catastrophic case failure, be aware that there could be pieces of extractor ejected along the right hand bolt lug way, along with bits of brass and high velocity gas. Probably never happen. But if it does...
Another option would be to buy a magnum bolt, and sell yours.
Or, but a PT&G bolt body and install a custom handle.

I'm in sort of the same situation. I have a M722 bolt with pooched extractor/extractor cut. It could be opened to .308 size. And a new extractor would have to be fitted.
 
Buy the gun made in the calibre you want. Custom work on some guns devalue 's them, sometimes it doesn't.
Cost's of conversions could be more than buying a different gun

In my opinion it's the worst thing you can do to an original 700 extractor system. The M-16 extractor is better than a Sako extractor but the original 700 is much better.

Originally the conversion was done to accommodate the PPC case on a 700 action... Why only part of the Sako extractor system was used I don't know. Perhaps the idea that the Sako "bolt guide" was actually a safety device escaped those who pioneered the conversion, or the fact that catastrophic case failures are rather rare.

The problem I have today with those conversions is very few of the owners know what they are getting into... perhaps many of those doing the conversion don't realize it either. I simply wish if you are thinking about having the conversion done you have the facts before hand.

The design of the Model 700 action is superior to any other mass-produced 2 lug bolt action ever made , and that by installing only part of the extractor system from a Sako (2 locking lug action) completely compromises that design. The alteration does not make it happen. But the alteration is completely unsafe when it happens. We are talking about a catastrophic case failure. They do not occur on a regular basis. (In the US there have been serious injuries and at least one death associated with this conversion).

A Sako extractor is safe in a two lug Sako so why shouldn't it be safe in a two lug Remington? ... Because when people install the Sako extractor in a Remington they do not install the Sako bolt guide, which is the safety design incorporated in the Sako. That bolt guide is there to protect the shooter and anyone close to the shooter if a case fails drastically. I do not understand why anyone would knowingly install only part of the Sako system. If the Sako extractor and the Sako bolt guide were installed then the Remington would be as safe as a Sako. Not as strong and safe as the Remington was before alteration but safe.

Here is a picture of how well the Sako "bolt guide" deflected/prevented debris from exiting down the bolt raceway...

Opening the bolt face to a magnum and using the Remington system is a bit complex and a little fussy because there is much to work with. By the time the machining is done, there isn't a lot of material left in the bolt nose. Using the M-16 extractor is simply easier and this is why people do it. The last few I've done, I used the Remington system but I have to confess, I don't love doing it.
 
Bill, back in 2002 I copied this from a forum and kept it on file. Wise words from a wise man...

Opening 700 bolt face to magnum…

I will describe from the viewpoint of looking straight on at the bolt face.

The bolt is set up with the lugs 8 degrees clockwise from being vertical.
The ejector is on the bottom. Assuming the bolt face has been opened to .525 we'll use a .500 dia woodruff cutter ground to .112 thickness.

We'll start by moving to the right to contact then cut .050 deep.

Then up .060+.0125. Then left .120. (.050+.025+.045).

That should do it.

Yeah, that's it alright and it works fine but, every time I do one, I half expect the cutter to come through the side! Very stressful! There isn't much room for error.

guntech-
Imagine the outcome if that SAKO pistol powder load was run thru a Winny,Salvage,Ruger,Bergara or any of the other cheaply manufactured rifles made today?


Any improperly machined SAKO extractor modified push feed bolt that I've had in hand to include from manufacturers that the extractor pivot counterbore was machined thru the body allowing witness of the firing pin is a refusal of services from me & is returned...w/ my finger prints wiped clean from said JUNK.

I agree on the stress... I won't alter .308 faces to magnum anymore... last one was many years ago...
