And there are several different extractors for the 700 depending of the year made. IF it is screwed up, best to send it to Remington and they can replace it with the right one. I had a pre-69 one, and NO more extractors, after they used the last one to replace mine with, so would have to get a Sako style if it got broke again. Have been told there are ones out there, but never been able to find the right one for mine, and finally sent it to Remington. This was back in 2009, and was going to Africa so had to borrow the bolt from a friends rifle, and have the local smith check head space , which was fine, till I got back. I'd let a smith get the case out, if it is sticky at all. They have the tools and knowledge to do it right, and not going to hurt anything. One thing, is, the 700 one of the strongest actions in the world, and was tested by the Army and a case full of Proof powder, with a 180 gr bullet and 5 more 180s pushed down the barrel on top of the load, was unable to blow the action. At that level finally did bulge it. Obviously the gass handling worked well. I was at the range several years ago, doing hunter sight in and a guy had had his M77 in 270 "bore sighted". Told folks to quit talking to the man doing the bore sighting while he was working. He'd pulled the target thing off the "spud" and a cease fire called. When hot was called again (people talking to him), He glanced over and didn't see the target piece, so gave the man his rifle, who went to the table and put one down range. Unfortunately the spud was still in it, and found 50 yds down range, and locked the gun up, and split the stock behind the action, etc. But didn't come near blowing, and gas correctly diverted so no one hurt. Unlikely guns made since 1950s going to ever blow. Hope you get the problem taken care of. But take it to a smith to do. How much over was your load. a Balance beam scale not ever going to be off. Well, can be but that's why they have the check weights and a bullet of known weight can also be used. The beam unlikely to be off a whole grain though.
