.22 ammo sensitivity
I was recently shooting one of my Iver Johnson TP-22s when a round fired while being chambered. The trigger was not pulled and the hammer did not fall. It just went boom when the slide went forward.
I recovered the casing and it has no trace of a firing pin strike or any other mark. The shell looks just like an unfired casing.
Has anyone here experienced something like this? I can only assume it must have been an over-sensitive round. With the priming compound being in the rim as opposed to center-fire rounds I know these can be set of easier but this is too much. It was a Federal .22lr.

Just my opinion but I also have one of the TP22 pistols and the extractor would be capable of impacting the rim as the bolt closes. Just consider yourself lucky the case didn't blow out sprinkling you with hot brass. Flush the crud from the extractor area and lightly lube with RemLube or similar. 0 -
Had a Marlin 39A with NO firing pin fire- when the hammer dropped on the bolt. (Repair of rifle, checking feed, FP removed) A bit more sensitive than the average round, maybe extractor transmited some energy- but if fired- with no mark at all on the cartridge head or rim. One round of maybe 100,000 I have run thru 22 firearms. Which goes back to "Always point a gun in a safe direction". 0 -
this is alot more common in the match chambered barrels like the target barrels for ruger 10-22. i have had several that blew the extractors off when the shell fired before the action closed completely, that is why the makers recommend target ammo. it is loaded to tighter tolerances. 0 -
Sounds like the rim was FAT or larger in Diameter You may also have Battered the breach face of the slide making the head space less then it was when new. I did have a Kart conversion unit with over 500,000 rounds through it start doing the same thing I had to take an endmill and deepen the breach face cut about .006 inch. I would not use the pistol until I had a Good pistol smith check the head space this gun could get someone killed 0 -
Not to get too mercenary about the whole project, but when I've had problems with ammo; misfires, mostly, with no apparent cause like light pin strike, I've contacted the manufacturer and on several occasions; different makers, have had them request a return of offending round and have then sent me 1 or 2 bricks of ammo for my trouble. Winchester and Remington, for sure; maybe Federal once. I'm sure CCI would do the same, but I've never had any problem with their ammo. 0
