A son-in-law inherited a Remington 552. It looks great: no rust, no scratches, no dings on the stock. Beauty is only skin deep however: it has a feeding problem. A U-tube video showed me how to disassemble (no small feat) & I found a heavy round lead deposit @ 12:00 O'clock over the chamber. That deposit was about 3/16" in diameter & difficult to reach. The only way to reach & remove the lead was with a pick (a slow process). With about 80% removed I got down to a harder metal roughly a rectangle in shape. That harder metal is the substance of this post.
Has anyone out there ever noticed such a deposit over the chamber of a 552 ? I don't want to remove something that is supposed to be there.
I have posed the same question to rimfirecentral about a week ago & have not received an answer.
Any help would be appreciated: I'm desperate.
