My first double was an Ithaca/SKB Model 100 20 gauge 28" M/F($188). I shot a lot of ducks with that gun and Federal 3" #6 and #4 for the second shot while drifting down rivers and sneaking up on farm ponds. The advent of Non-Toxic steel put the gun to rest. It also performed quite well on pheseants and everything else that flew or ran and was legal. No problems with recoil, gun was just over 6#'s. I guess the birds and critters never looked at a pattern board or read any of the Sports writers!
Now have Win Model 21 3" 20 gauge! -Dick
