Would like advice. Son in law wants a 12 gauge O/U for sporting clays. He is new at this. Budget is up to $2K. I suggested either a Browning Citori or Beretta Silver Pigeon. I'm thinking a 28" barrel but not sure about the plusses and minuses of chamber length. Seems 3" is popular. I have a 20 gauge Remington 870 I bought 39 years ago and for the very limited shooting I do it is fine. He wants to go to the next level. I lean towards Beretta for the super quality they make, but would appreciate suggestions/comments. Thanks.
