Well, for Christmas my son inherited his grandpas Marlin 89C . He's quit excited. The only problem is, the shell won't load into the chamber. It looks like the bolt does not slide back all the way when pulling it back. It disassembles quite easy. And gave it a good cleaning. Inside the bolt,where the spring inserts,there is a rod that looks slightly bent. Could that be why it's not coming all the way back?
