Re: Stovepiping ruger 10/22
I had the same problem with a 10/22 build that I did last year.
If you are using a match grade chamber, alot of times the extractor needs to be tuned to eliminate the stove pipe issues.
(I had the same problem even with a VQ Extractor.)

The author of this article also sent me an update:
<div class="ubbcode-block"><div class="ubbcode-header">Quote:</div><div class="ubbcode-body"> Since writing that article, I've been tuning extractors an easier way.
If the hook shape looks okay, I just clamp the hook in a vise with the rear hook upward, heat the rear lug to dark red, and tap it gently toward the hook.
The amount it's tapped depends on how loosely a casing is held by the hook. There shouldn't be any play and the hook should hold it firmly against the bolt while pushing it against the opposite side of the bolt recess. If it's too short, the hook won't clear the notch. If that happens, grind or hone the forward part of the extractor lug to make it fit properly.
If you don't tap hard enough to shorten the hook to lug space enough the first time, it can be redone several times until you get it right.
The advantage with this simplified method is that the hook never loses temper, so it doesn't need to be re-hardened. Sometimes re-hardening doesn't "take", so this is usually a better method. If the hook shape needs to be bent to better grasp the case rim, the method shown on the website should be used.
Good luck with your project.

I tuned mine by using a vise to slowly push the tip of the extractor further over without using any heat.
(Flat side on one jaw and round side on the other.)
When done properly, the extractor should hold the cartridge tightly against the bolt face and have minimal play.
This issue drove me nuts until I came across that article.
(I tried three aftermarket extractors and had the same stove piping issues until I tuned it.)
