FTExtract?

[Robb]

Out to the range today and ol' Reliable let me down, huge. I picked up a battlepack of pmc ammo on the way. I can rack a round into the chamber and fire it and then I get a failure to extract, a 2nd round feed and of course a jam. I clear the jam and it happens again consistantly. Last time I had this rifle out it was flawless and always has been.

Nothing has changed with this firearm in years. I tried numerous mags today and the problem continued. The same mags worked well in other rifles today.
I pulled the bolt and nothing is broken, the extractor seems to have good tension, the hook or claw seems okay, carrier key seems fine.
What's up? Is a bolt rebuild on order? Will a new spring fix my problem, or is it something else?

Any help is appreciated.

Is your bolt a bit bulged at the bottom edge of the extractor ? Or maybe just light & shadows playing a visual trick.
all I have to offer is " Go see Bert, Go see Bert, Go see Bert" ( sung to the Cal Worthington commercial tune ).

I see what slideshow is saying as well... Try a new BCG

That would be SideShow..........

I see what your looking at with the 'bulged" bolt comment. I'll take a closer look in a bit.

"Nothings changed for years".....
Like the gas rings?
Clean the bolt and carrier. Reassemble it without any lubricant and extend the bolt fully. Set the BCG on the face of the bolt vertically. If the rings have sufficient tension the rings will support the weight of the carrier, if not the carrier will drop.
You state that this malady started with this particular lot of ammo, that would be the first suspect. I have seen more ammo related issues in the last couple of years.

Yes, sadly I've been bad with maintenance. The rifle has the original gas rings in it I'm sure. I'll do the bolt test tonight! Thanks for reminding me about that.
I picked up some PMC ammo on the way to shoot. It was only an issue in the rifle I'm referencing. 2 other rifles ran smoothly.

If the ammo was a tad weaker than what you were running and add weak gas rings to the mix.

Thanks Bert,
I'll order a few bolt rebuild kits & gas rings and try to refurb the bolt, never done it before! High time I learned how.
