this topic recently came up in another thread...

in my experience, i have only had this happen once...

it was a sleeved 16 ga english boxlock, made by one horatio jones, who was a small gunmaker, located south of liverpool...

anyway, the action included double under lugs and a third hidden fastener...

sent the gun to a well qualified smith, who rebuilt the bolting system, and all was well...

care to share your experiences here?

keep it simple and keep it safe...
