Rem 700 Primary Extraction RR serial #

[DJ Fergus]

Not just the RR rifles. Extraction with magnum sized cartridges in the 700 goes way back and is highly common. There are instances where some particular magnum 700 rifles have never had an extraction issue. It can be fixed as factory state to extract. It's usually around $50 on your dime to have it fixed that way. Or have it fixed on Remington's dime if you find a Remington authorized repair shop you trust. I just went ahead and paid to have an m16 extractor put in. Kampfeld customs in Sandpoint Idaho will do it for $120 and you will be happy you went that route. Karl is a really friendly and dependable guy. Normally very quick turnaround also.

The brass is ADG and the load is a full 1.5 grains lower than Berger's max. Chrony is reading 50 fps lower than Berger's max. Before the chamber was polished, firing virgin brass gave soft ejector marks at random on an order of 1 every 3 cases. After the chamber was polished, second firing with 0.002" bump with FL die, the same powder charge gave consistent ejector marks on 8 out of 10 cases. Case length is good along with COAL at 10 thou jump. Seems like a pressure issue at the core of it. I'm not sure the chamber isn't at fault some how.

Before polishing, the gloss on the brass was taken away with the first firing. There was some texture but no scratches, dents or the like. After chamber polishing, the second fired cases have a shine, but I can still see some texture...maybe from the first firing? I bore scoped it and didn't see any glaring defects. Maybe the sand paper job in the chamber was a bit too aggressive??

...or maybe its just the reloads as factory ammo seems to work fine....if some can be located right now.

Appreciate the input

Read the last line in that quote. If factory has no issues, it's your reloads....

The issue does seem to be getting worse as time goes on. I did a complete clean of the barrel and action with no improvement. To me, it sounds like the load should be reworked. Not sure if the barrel "sped up" and now has more pressure with the same charge?? I'm not sure that is what "speeding up" means.

About 8 years ago, I bought a new rem 700 and it had the same issue with factory ammo with every shot sticking. Sent it back to them and they sent me a whole new barreled action. I wish I knew what they found to warrant such a major fix. My other guns can withstand a very hard bolt lift with bright ejector mark and the cases still extracts. Could the chamber be messed up some how? Too much head space, not enough web support, too rough...or maybe its just the reloads as factory ammo seems to work fine....if some can be located right now.

I don't have much more to add, but I personally would start measuring your prepped brass and comparing it to factory ammo/brand new brass. I'd also confirm it chambers with zero resistance with your ejector and firing pin removed. Good luck, I'm curious what you figure out.

I tried the factory and reloaded ammo in the chamber without the extractor. No resistance I could tell. I'll still compare the sized cases vs. factory when factory rounds become available. Dies are Forster comp dies with micrometer seater.

I agree, but want to cover all the basis due to my past experince with that 700 and not knowing what the problem ended up being.

Thanks for all the ideas.

I'm probably going to get flamed but, I actually fixed it myself. It wasnt the voodoo that I thought it was.

A little heat to pull the handle off, a set of feeler gauges, a heat sink, a modified vise grip, and a tig welder is all that was needed.

I moved the handle forward by .015" to a gap of .010" between the front of the handle and the cut in the receiver. I advanced it slightly to get a little more cam action between the two surfaces and tacked it in place to test it all out.

I put a piece of tape around the case head to simulate a case that needed some extra primary extraction. The bolt was sticky all the way up to the came action and it ripped the case right out.

No issues to report. All is good in the neighborhood.

Another benefit...
the bolt handle will never separate from the bolt body after welding it on there.

Nice looking weld, BTW.
