The first onetook over two hours. But by time I had done a dozen or so, it wound up being about a 45 minute job; half of which is set up time.
These generally come out best when you are also opening up the bolt face. If not, then the groove where the factory Remington extractor went needs to be filled in with JB Weld to keep the case rim from wandering into this recess.
So if I sent you a bolt from a 300RUM, to have a sako extractor put on, you would need to put some JB weld there?
