they are just different enough to screw everything up ...


I came to find this to be very true.
I bought a nice used 77/22.
Durn thing wouldn’t chamber a round unless I pushed up on the magazine.
I sent it to Ruger with a note.
They sent me a correct magazine and an explanation that I was trying to use a 10/22 mag in a 77/22.

I always knew I was ignorant, but this was a surprise to me.
