Hey guys.
I have an old cooey 64 semi auto .22 rifle.
I have always had failure to load and failure to extract issues with it.
After plinking today I decided to clean, and look at it.
Looking at the top of the mag, I noticed that it was worn shiny.
The bolt shows sign of the edge hitting the top of the mag.
The only solution I have thought of trying was to shim the mag holder or grind the mag a bit, maybe chamfer the bolt edge a bit.
Since there are so many of these around, what have you guys done?
Surly I am not the only one.
