RE: 16 guage
Personally, I have never seen 16 ga at any store in recent memory, and to be honest though, I haven't been shopping for it. I do every now and then, depending on the sports store, if it is one that I have not been in before just take a look to see what off the wall ammo they have.It helps me for future reference when i need something special that I can't find say at wally world. IMO if they have the specialty ammo, then I can expect that they will have some of the other more specialized euipment too.
