IThanks for the replies Guys
It is a 6.5 Saum, this rifle has a Shillen #2 or similar profile barrel with carbon stock & easily shoots sub 1/2 moa & always has, quite impressive for such a light rifle.
It doesn't appear to be overloaded, but I don't have access to the brass, which has only been fired in the rifle.
I can't get a bore scope into the rifle as I don't currently have it.
It wouldn't easily extract two bits of fired brass I got back with the rifle at one stage.
I realised the brass was dirty & probably the chamber was as well so gave the chamber a clean & quick polish with Autosol, after which the dirty brass extracted flawlessly
I think after a year or so the chamber is dirty again possibly due to cleaning fluid contamination or water etc (this is a hunting rifle) or the stuff off dirty brass being forced into the chamber again, seems to have be happening since the rifle was built
The owner is adamant it is solely a primary extraction issue
I find this hard to believe considering the brass was left behind in the chamber when the bolt was opened & hit back,
In my opinion no amount of primary extraction will help if the case is stuck so firmly in the chamber that the rim is torn off or the extractor cams over it, requiring a cleaning rod to remove it from the chamber ?
Your thoughts ?
Can the Rem 700 primary extraction cams be hurt/damaged by repeated abuse ?
I had a Remington 700 7mm Remington mag that didn't want to extract sometimes. It had the factory extractor. I had a mini m16 extractor installed. It extracts easily and flawlessly now. The case doesn't even try to stick.A custom Saum Rem 700 SA that has had the primary extraction fixed is refusing to extract a fired case from the chamber again.
This rifle was working great, extracting just fine after the chamber was polished but over many months sitting in the safe & with use it gets worse & worse
The bolt will come up but when the bolt handle is hit to remove the case it is reluctant to come out or stays in the chamber with the extractor partially ripping the rim off requiring the use of a cleaning rod
Is this a primary extraction issue ?
Is the dirty chamber & or brass issue ?
The load has been backed off but there is possibly a carbon ring/build up
Any ideas on this ?
Yes that is correct. As a result of previous repair attempts is was not possible to reposition the handle on the bolt body again.Sorry, when you said "No primary extraction" are you saying that primary extraction was the issue?
