I found two unopened boxes (plus 12 loose shells) at a local flea market for $100. Probably paid too much but I have a shotshell collection that didn't have any 2" shells in it.

I am considering opening one box and hunting with them in the Fall. Is this a good idea or bad? I have a couple of cases of RST and Polywad 2-1/2" shells that I usually hunt with, so I don't NEED to use them, just thought it might be cool to see how they perform. Any advice or thoughts?
