A friend stopped by with a 73 in 22 short last night. everything is in order except the loading tube. You have to remove the tube and insert the shells, which is normal. His problem is that the shells won't stay in the tube after you take your finger away. It seems there is a detent missing from the aft end of the tube. Maybe we're doing something wrong?

Does anybody have a picture of what it should look like, or know a book I can reference?

thanks,
