[QUOTE="SMK1000plus, post: 1617987, member: 93846"] You are lucky to still have a face! EXTREME over-pressure! Wrong powder? Wrong, oversized bullet? Remington 700 you say? If so your extractor is already ruined. There won't be any spring left in the extractor metal. You can still buy the replacement extractors from Remington and, if yours is the riveted type (most are) the rivet too. It takes a special rivot anvil and a small steel hammer to brad the rivot into the bolt properly. Make sure you get the right size replacement extractor! There are several sizes, dependent on cartridge base diameter. To remove the brass, use pliers or a vice and crush the brass a little at a time, from each side, as close to the base as possible without hitting the bolt. It will still be hung under the extractor recess in the bolt face, so you will have to wiggle it firmly, until it gives and comes out. After you remove the brass, you'll need to measure the very front diameter of the bolt, in front of the face of the bolt. If it is a standard Remington 700 bolt, the diameter should be between .695" and .702". If it is any larger than .702", it should be checked by a COMPETENT gunsmith! The bolt may be ruined. If the diameter is .702" or under, you will need to check your headspace with a good no-go gauge and possibly a field gauge. If your bolt closes fully on a field gauge, the rifle is unsafe to shoot. Again, get it to a COMPETENT gunsmith. He may be able to save the barrel, maybe not. Don't neglect to check the barrel for bulges, action for cracks or warping and even the stock, especially at the recoil lug and action screws, for damage. Any way you look at it, you are way more lucky than your rifle. [/QUOTE]
