Just curious, how does one determine that they have the .730 barrel, it is a Mossberg 500 SP.
According to what I find here
http://www.dixieslugs.com/forum1/vie...50b7e1b1cb479f it lists the 500 as ok, but mine does not take a choke, are all 500s the same minus the end of the barrel, or would there be another resource for finding this out?
