I carried a 12 gauge 870 Rem with a Rhino tube and 3 inch Environmetal 4X5X7 H378 loads for several years. Great combo to say the least. Killed many a bird with it.

Last year just for grins I put a PureGold .555 tube on the wifes 20 gauge Remington 870 Express, picked up some Envirometals in straight 7's and added a Red Dot.

I gave up nothing with the little 20. Denser patterns at 40 yards, and the result, bang, flop, at distance greater than 40, although I don't advocate long distance shooting with any gauge shotgun.

No more lugging the 12 around for me. In fact no more 12 period. Sold the whole thing lock, stock and barrel, as turkey hunting was the only thing I used it for.

Count me as a big fan of the 20. Properly set up for turkey hunting, it'll do anything my 12 ever did, and a whole lot easier to tote around, which is definitely a plus over a long season of running and gunning.
