I have three Remington Custom shop rifles (a Model 700 Safari in 416RM and two Model 700 Custom KS Mountain Rifle both in 375 H&H and in 7RM) to which I am willing to "update" with the Sako extractor type.

Now, in Midwayusa a PTG bolt body only is offered, which simplifies a lot the conversion work, mainly considering I am in Argentina where I still have to find a gunsmith experienced in this type of work...

But I am not sure which bolt body should I need for the mentioned calibers, being the available choices as follows

*PTG Bolt Body Only Remington 700 Long Action Magnum Bolt Face for Sako Extractor Steel (http://www.midwayusa.com/eproductpage.exe/showproduct?saleitemid=118214&t=11082005)

*PTG Bolt Body Only Oversize .7025" Remington 700 Long Action Magnum Bolt Face for Sako Extractor Steel (http://www.midwayusa.com/eproductpage.exe/showproduct?saleitemid=259894&t=11082005)

Suggestion will be appreciated !

It appears to me that the first one listed is probably a standard diameter bolt which should be somewheres between .690-695 and the second is slightly oversized which might require reaming the bolt tunnel's to fit. Unless you have a gunsmith who can ream the action, then of the two bolts listed, you would be better off with the standard body diameter for all 3 guns.

If you can find someone who can accurately measure the existing bolt tunnel for each gun, you can order custom diameter bolt bodies from Dave for, I believe, the same money. You can order the bolts complete with handles installed for not much more than what yjr body is listed for at Midway.

The problem will be fitting and headspacing these bolts to your actions. Not really a problem but one more expense you need to plan for.

Your best and cheapest bet would be to have the extractors installed to your existing bolt's if you can find someone who will do it correctly. Good luck!

I am a fan of the Sako extractors. With that in mind, I have to ask, why do you want to upgrade to that extractor? What are the implications of sending the bolts out to someone who does the conversion, say to the US? If the originals work?????

I think you will have problems with the brass hitting the scope. I've been there, I put one in a 375 and ended up swapping bolts. There is nothing wrong with the factory extractor. If you want PM me and I will send you a bolt to try. If it ejects OK and you like it you can possibly fit it to your action (gunsmith only) and pay me for it or if nothing else you can see if you like it with nothing lost. Also I modified it for a NECG safety and it has a sleeve on the rear to tighten it up a little. Factory receivers usually run .702-.704 in the back

There is a trick here, don't use the magnum extractor, use the 308 size and you will eliminate the problem.

And the departure angle is easy to adjust.
