In reverse, as the bolt begins to open the spiral slot rotates the bolt head counter clockwise out of lock position.īanging a rod down the barrel, into a spent case against the bolt head will not unlock it. As the bolt closes on the chamber the bolt head is forced to rotate clockwise in the spiral slot locking its lugs into the receiver. Part E rotates inside part D by way of a spiral slot and pin through G.

Part A and D are held stationary to one another by a pin. The bolt is in three major pieces: bolt body “A”, locking sleeve “D” and the bolt head “E”.

Dropping a rod down the barrel on a spent case will not work, yet. Beating on the cocking handle will only result in something broken or damaged. What to do? You cannot remove the stock on these rifles to get at anything, unless the bolt is retracted, which you cannot now do with a bolt stuck closed. That issue is one of a bolt stuck or seized against the chamber with a spent case in the chamber, live round or even empty chamber. 308, Winchester Model 100, but this information may apply to other calibers in that model that may suffer the same issue. I understand Winchester may still be honoring the recall.

This issue has nothing to do with the firing pin recall on this rifle, but is something you may want to look into for other reasons. Unlike gas operated military firearms that are designed for severe conditions of use, and irregular maintenance, gas operated sporting firearms are built to closer tolerance, equivalent to their intended use and can be temperamental with regards to cleanliness, lubrication and even ammunition. Trying to help a good friend with this issue, I decided to write this post because there is a lot of useless and even bad website information on the subject.
