Years back I was head set on setting up and over/under to turkey hunt with...after going through three Browning's a Beretta one American arms and one Fabarm I finally gave up...the bottom barrel on all of them patterned from 6 to 9 inches low at 25 yards progressively worse at longer ranges.

The only manufacturer I contacted was Beretta they said 9 inches low was within their specs. I think what they are banking on is the average guy will never check point of impact on a shotgun.
