Gets a little confusing doesn't it?, my 3in magnum has a 26in vent rib barrel that is marked as capable of firing 3 1/2 in shells as long as its on a supermagnum receiver. I know the non-supermag barrels (3in) will work with an 870 supermag as long as you only use up to 3" shells.
I have also read that supermag's do not perform as well with the 2-3/4" to 3" shells due to the exta spacing in the chamber as the shot has more room to become deformed before leaving the barrel and that makes me wonder why Remington would ship out standard 3" expresses with a supermag (3 1/2")barrel.
This leads me to believe the only really difference between the express magnum and the supermagnum(other than some internal parts and a longer cycle) is the strength of the receiver, eyeing both the receivers seem the same size. I guess I would prefer a barrel that was specifically designed for 2-3/4" and 3" shells versus getting a barrel that has blanket coverage for all 870's.
Anyone have any input on this?
