I had a similar problem with one of mine. I bought that pistol when they came out for the first time (the Govt. target slab sided 6 7/8) and it could group better than a ruger 77/22 rifle at 100 yds scoped and benched.
Any way, apparently while using a thick toothbrush to clean it internally, I may had pried open a little the fixed point that supposed to hit the spent cartridge as it is blowing back the bolt. Well, mine started to get wedged on it and the gun will try to load the new round while the spent shell jammed "a la stove pipe" style. It took me a long time to figure it out and even bought a brand new bolt from Ruger, thinking that the bolt had the problem somewhere.
Since I have three of those pistols, I decided to examine each one point at the time and compare. I disassemble the gun and removed the bolt and look down the barrel to see the alignment of the pointy thing that kicks the spent shell off the gun's extractor. The pistol with the problem was bearly showing the poit while the one that work fine it showed the pointy thing very clear. That's when I noticed that that pointy thing is held together by a ribet and when I cleaned the gun with a thick brush, I had moved it enough so that the spent shell actually wedged itself in it.
I use another tooth brush being careful not to break the pointy fixed thing and incredibly, I could now see it down the barrel. That pistol has not had a hickup ever since.
I, by no mean am a gunsmith; but that is the story of my situation that has similarities as your story.
Camba.
