Cant go fishing at the moment.

That doesn't seem quite right - how could there be a slot cut in the barrel for the firing pin? Setting off the round requires support of the case rim under the firing pin - a slot would seem to be counterproductive. There is a slot for the extractor claw, and there may be a firing pin stop within the bolt to prevent over-extension?

I don't have a 10/22, so feel free to correct me on this.
