Hope this doesn't come across as stupid. No stupid questions, Right?
If I buy a new 870 Express the receiver is marked 2 3/4 and 3". Does this mean I can use either in this barrel. Or, does this marking only refer to the receiver and I will need separate barrels. If the chamber is cut for 3" will extended use of 2 3/4" harm it?
I never had this come before up since I have only used an old Wingmaster in 2 3/4 till now.
Also, should both 2 3/4 and 3" feed and chamber with equally reliability?
