Take it to your favorite accomplished gunsmith and have him put a SAKO extractor on the bolt... Otherwise, make sure that the little dinky extractor inside of the bolt face doesn't have a bunch of brass and crap built up behind it...
The Saco extractor conversion isn't worth the money... Remington extractor problems keep being "repeated" over and over even though 99.99% of 700 owners never have even one problem with there extractor.
I build my brown bear rifle around 1980 on a 700 Rem. rifle, and it's worked flawless since then. It's hammered more than one bear along with all kinds of other big game i ran into while out in the bush. I have several other 700's too, and none of them have ever had an extractor problem.
This guys bolt needs to go back to Rem. and be fixed properly, probably for free, and if it's like my 700's, he can forget about having any problems with it.
