Hey guys, a friend of mine is sending his old Delta.68 to take a look at, as it's not recocking properly after firing. He says the piercing pin seems to be fine, as it's not leaking, but the velocity is very low.
Having not seen it yet, I'm not sure what to suggest, so I was wondering if anyone could give me a few pointers so I can think about what I might need before it gets to me.
Apparently, it's been spraypainted and some of that's got on the bolt (he, uh...didn't disassemble it
) so that could be the problem.
Any advice would be much appreciated.
