I am interested in upgrading the barrel on my 1970's vintage 20 gauge 870 Wingmaster. It currently has a plain barrel with an improved cylinder and 2 3/4 chamber. I would like to replace this with a barrel that has the replaceable chokes and a vent rib. Since the chamber is integral with the barrel, can I install a barrel with a 3" chamber? Or is the receiver not long enough or strong enough for this? What about magnum loads? Thanks.
