I recently purchased a 1903 that I found had been converted to 22 LR. I ran dummy rounds through it and it fed well, but often failed to extract.  I broke it down and polished  the extractor and tightened the spring and it appeared to solve the problem.  I took it to the range today loaded 4 rounds in the tube, cycled the action and pulled the trigger. The extractor worked great as it fired the four rounds in full auto and never failed to extract.SurprisedHelp,  any ideas on what happened? It was kind of fun, but probably illegal.

Check the firing pin sounds like it might be broken or stuck in the forward position. Yes illegal as well as dangerous.

cranky2,

Well I took apart the bolt cleaned the firing pin, every thing looked fine. Back to the range, bang, bang, full auto. Took it to a gunsmithCrywho felt there was a burr on the chamber where the round seated and was setting off the primer. Reamed the chamber, bang, bang still full auto. Try again with reamer still no luck. What is one of the things shooters should do?, Change the ammo. It worked and tomorrow I will test again.

Thanks for your input,

Bill

I took it to the range and Fiocchi  worked just right, and federal fired full auto.  It fires in battery so it appears to be safe. It appears the federal is a softer brass and when it slams shut it fires. Interesting observation.
