Remington 700 VLS chamber cartridge feeding problem


Registered Users do not see the above ad.


My brother owns a somewhat ‘troublesome’ .243 Remington Model 700 VLS (Varmint Laminated Stock). Since new, he has frequently experienced rather frustrating chamber cartridge feeding issues - to the point where he’s now seriously considering selling the ‘unreliable’ firearm. Note, he has unsuccessfully altered the feeding and extraction speed rates of the bolt in the hope of identifying the possible cause, in addition to loading one less cartridge in the ‘internal’ magazine so as to decrease the upward tension. In hindsight, we suspect that the problem might be related to the mag spring being out of alignment and / or incorrectly tensioned. Has anyone experienced a similar chambering problem and if so, how was the matter effectively resolved ?
Sincere thanks for any helpful advice.
Cheers, Ross.

Mainspring, the feeding problem appears to be related to a faulty extractor – as inferred by my brother’s following explanation :

“I loaded up the mag several times with four cartridges and with one up the spout. I ejected all the rounds and discovered that on average the bolt was not ejecting one in five rounds. Regarding the mag spring possibly being out of alignment, I noticed that there is wear on the right hand side within the mag wall. However, it would appear that the main problem that I can see is with the fact that the bolt is randomly not fully extracting the cartridge”.

Note, the rifle’s about 5 years old. Replacing the ‘faulty’ original extractor might possibly solve the feeding / extracting problem. Alternatively, he has thought of having a Sako extractor adapted but, according to the following related thread, it might be an unsafe option.

Sako Extractor In Remington Bolt--Safety Issues??
Are there serious concerns with installing a Sako extractor in a Remington 700 bolt? It seems that this has been done many times and there must be hundreds of rifles with this modification. Are there cases where safety was compromised when gas came back through the action?
To answer your question, yes the conversion will make your M700 "less safe" because it weakens the bolt head enclosure, allowing the potential for the extractor to be blown off the bolt in the event of an extreme overpressure load. Some gunsmiths will tell you that the possibility the extractor can blow out the right lug raceway back toward the shooter is great, others will tell you the conversion is safe. This really only applies to the M700 and other actions where there's an open path to the breech; it may not apply to some other actions that have baffles or other mechanical blocks sealing off the breech. One thing's certain; the conversion is not as safe, but whether or not it is "UNsafe" is a different question.

It's probably the cheapest option to replace with another Rem extractor, just a thought.... if that doesn't work then you aren't out much.

I wouldn't spend too much time messing with the mag box for an extraction/ejection issue, unless there is something blatantly visible.

Do check the ejector, that's the plunger in the bolt face. Crud and brass have a habit of building up inside the hole and don't allow the ejector itself to move freely for it's full movement of travel. Pushing on the plunger with a punch should feel heavy, but not rough.

The extractor itself tends to shave small fragments of brass which become caught and bind the extractor from moving freely. Use a good copper solvent and let it eat away at any brass in the extractor area. Again, a punch can be used to check free movement by pushing on the extractor.

Clean the chamber really well, try and eliminate any crud and rust that may be causing the case to stick slightly.

Ammo, reloads? Check for overloads and double check case length.

With the bolt removed from the receiver, insert a case under the extractor. It is a bit hard to hold pressure against the ejector, but try to hold the case flat against the bolt face. Now try to slide the case out from underneath the extractor hook. The extractor itself is also a spring. If the case can slide out, the extractor may be bound up or have lost spring tension. If tension is gone it's time to replace the extractor.

Replacing with a Sako is a personal choice. It sounds like you've seen the pros and cons, I personally don't have a preference one way or the other. I would look at the availability of parts and use that as the tie breaker.

At the risk of sounding like a broken record , Polish your chamber with any good metal polish ( after a good scrubbing of course ) and your issues may vanish . Remington extractors are either broken or they aren't !
