RE: 12 gauge 3.5" or 10 gauge what do you perfer?
if you have 3 other 12s well then i would say stick with your 10. reason is that a 12 ga. 3.5 is good for the versitility like clays, rabbits, ducks and geese. the 10 has the same charge as the 12 3.5 (look in a cabelas catalog), except for one thing...the patterns are generally better simply because of the fact that the barrel is bigger so the shot has less resistance on its way down the barrel.
