My friend decided to build nice .308 rifle based on rem700. He is going with AI stock, Jewell trigger, Badger floor and rail. All that will be left out of original rem are receiver and bolt.
When I was building my rem I based it on LTR and the only reason for that is coz I happened to find nice used one locally for $650.
LTR tend to cost +$1K when new. Since my buddy is going to replace everything except receiver I'm wondering if rem's receivers are different from model to model. I noticed that people for some reason tend to choose LTRs for their build-up projects. Why?
 
Remington 700 actions only vary in external finish and manufacturing tolerances.

I really suggest having the action trued prior to re barrelling to correct these manufacturing "mis-tolerances".

A re barrelled 700 usually will shoot very well...

A trued, re barrelled 700 will usually shoot extremely well...

Why an LTR? ... just the black rifle craze...

That is what I thought. I'm not even sure if there are any tolerance's difference on different models.
When it comes to a truing - I agree with you 100%. It is one of the "mast have" things to do.
 
Why buy the remington ???
I built my 6 BR off of an XR 100 remington, Gun was new at $1100, I now have a barrell i don't need and a trigger i don't need, the action had to be trued and we added a sako extracter.
The next gun I built was a 6 PPC, instead of paying MORE for an action and having spare parts lying around I bought the BERNARD "s" action from Ian at Robertonson composites for less and didn't have to do ANY machining its a copy of the Reminton.

So, what would be a downside of it? Are you referring to its ability to occasionally fly?

"To occasionally fly" is making light of a very serious occasion.

The alteration completely compromises what was the strongest, safest action ever made, making it less safe with a catastrophic failure of a case than any Sako rifle. (The two lug Sako rifles use a "bolt guide" to block the shrapnel and keep it out of your head)

There is no upside to the conversion as far as I know.

The 3 rings of steel have been discussed a lot... http://www.benchrest.com/forums/showthread.php?t=54852

It dos not cause a problem... it becomes a huge problem if you ever have a case let loose... Why would you alter the strongest, safest extractor system ever made? Just because you can? What advantage is there?

I recently was sent a photo and a short letter from a fellow in the US who said he has several 700's with Sako extractors. After having an overload let loose and reading about how strong the original 700 extractor system is, he is in the process of replacing all of his conversions with original bolts.

He felt very lucky his left handed girlfriend was not behind this one when it let go... no pieces where ever found... they would have been in her head or through it if she had been behind it.

The sako conversion offers no support whatever to the case with an overload.

I have owned six 700s with sako extractors and have never had a problem of any kind.I started using sako extractors after a factory 700 extractor failed.
 
How about a side-by-side picture of the two types for those of us in the dark? Anyone?

Edit: Just answered my own request...

Would my Stiller Predator, with it's Remington-style bolt and Sako extractor leave me as vulnerable as an original Remington with the Sako mod?

The second image above is of a T/C Icon, and I am supposing that the shoulder further down the bolt would prevent shrapnel from escaping.
 
In the course of the operation of my gunsmithing business, I have replaced Remington extractors. I have also seen broken Sako type extractors, Mauser type extractors with the lip broken off, as well as broken Winchester and Savage extractors.
Almost invariably, a dirty, rough, or neglected chamber was the contributing factor in these failures. Overloaded cartridges can also be a problem.
I have also seen rifles which experienced catastrophic case failures.
If something is going to go wrong, there is no safer commonly available rifle than the Rem. 700 type rifle. That would include 600, 660, XP100, XR100, 40X, Model 7 rifles, of course.
If a shooter, or gunsmith, chooses to compromise the design integrity of the Remington, and makes the decision to do so in full knowledge that there could be consquences, that is their decision, and they are assuming responsibility for any unfortunate results.

That was not the case when I had an extractor fail.The gun had only 30 rounds through it when the extractor failed.The gun was thoroughly cleaned before being fired,and the chamber was very smooth.The loads were mild starting loads .
 
A surprising number of people do not understand the concept of what happens if you have a catastrophic failure of a piece of brass.

They also do not realize the Sako extractor conversion that is done to a 700 is not the same as the Sako extractor system on a Sako. It is only half the Sako system. All Sako 2 lug actions have a bar of steel attached to the bolt as a safety measure to deflect or help contain the Sako extractor if there is a catastrophic case failure. No one does this when they convert 700's. The extractor is free to blow out at 70,000 psi right down the right side of the bolt race way at many thousands of feet per second.

This is not possible with the original 700 extractor.

I have had as many commercial extractors fail of all brands as I have seen with Remingotn 700's. It is a complete myth that the 700 extractor is not reliable and extremely strong. There are many million of them working fine. You can hang hundreds of pounds on it. When an extractor fails to work it doesn't matter what make it is... it then needs a repair.

Here is a picture of the 2 lug Sako action with the bolt in place. Notice the large piece of steel on the right side of the bolt. This is right behind the extractor. This helps prevent shrapnel and deflect gas if a case fails badly. I have never seen this piece added with any Sako extractor conversion of a 700.

Here is a picture of a 700 bolt as it would appear within the barrel in a locked position. The nose of the bolt and the extractor are surrounded by steel. This in turn is surrounded by the action. The case is fully supported as no other action does. It is a superb design.

I think it is important shooters realize what they are doing when they alter the 700... and then make an informed decision. There are many conversion done just for the sake of doing them based on the myth the 700 extractor isn't reliable. Any make of extractor may need repair. I suggest repairing a 700 extractor keeping the original design is way better than altering it.

It is your choice, just make it an informed one.​

I have seen new rifles with extractor problems right out of the box... Remington, Savage, Winchester, 98's, and Sako's.. all were easily repaired keeping the original design.

wish i would have heard about this prior to sending my bolt away for the conversion. hopefully i live to tell about it.

The death associated with the conversion that was reported on Benchrest Central was a right hand rifle and a left hand shooter. Other right handed shooters have survived similar conversion blow ups. I would not stand off the side or behind of the ejection port of anyone shooting a conversion.

You are comparing a 2 lug action and a 3 lug action... an all together different situation in containing the brass ... the three lug Sako extractor is safer than the 2 lug Sako extractor in a Sako.

Here is a two lug Sako

and the two lug Sako and a 700 bolt

On closing the Sako, the long piece of steel rotates and positions behind the extractor. This is never installed on the 700 conversions...
