Rossi Youth Combo .22 barrel Firing Pin Indent

roadchoad

I am cleaning up this newly purchased .22/20Ga combo for my 9yo for Christmas. I noticed that the .22 barrel has an indent in the chamber where thw firing pin would hit. What is the purpose of this? I assume because of the size of the firing pin neede for centerfire cartridges that the rimfire barrel needs a relief? There is no peened metal around the rim, so it doesn't look like dry-firing gone bad.



Oh, and yeah, I know, it is a Rossi. If you feel the need to sarcastically remind me of that or knock my son's first rifle in any way, you know where to put your post. [:D]

It's there so that in case of a dry-fire that the pin DOESN'T damage the chamber

I have never looked at a Rossi but have fired 100's of thousand 22 rimfire rounds. Normally a rimfire chamber need to Pinch the rim between the firing pin and the chamber edge .If one would damage the chamber by dry firing causing a BURR and then use a file or other method to remove this burr it would leave a demple in the edge of chamber this would cause misfires. However your picture looks like the chamber was machined the way it is . If mine I would take a pair of pliers and remove the bullet and powder from 10 or so 22 cartridges and then install in chamber attempt to fire them and inspect the cases . If you dont hear a POP on each one then you can assume you will have misfires with any ammo you try to shoot. MAYBE EVEN a HANG-FIRE. [V][xx(]Good Quality Pictures by the way. [^]

Haven't shot it yet, but would hate to have it misfire on him for his first few shots. I'll see if I can sneak it out to run a few through it....
