[QUOTE="foreign, post: 1212944, member: 11896"] So I was thinking about timing actions the other day and had a thought. Ideally the bolt handle is as far forward in the cutout without binding so that the max amount of primary extraction is available. It also has to be timed so its not fighting the engagement lugs. Lets say that that's perfect. The thought I had is that when one sets headspace the go gauge is bearing on the bolt face. That's fine, but when you go to extract a case the extractor engages the case lip and if there is a bigger gap between the bolt face and the extractor than the rim thickness you are loosing extraction there. My factory Remington's are good, but one with a M16 extractor has slop and so does a browning I have. Do people think/ worry/ time the extractors? I'm thinking of soldering in an insert and then reaming my headspace a bit. Cheers [/QUOTE]
