Personally I do not consider ""a A-5 or 391 gas jackhammer would be the obvious choice over inferior sxs guns"" a SxS to be an inferior gun. True it will not hold as many shells, if one needs that many for a single head of game or a single covey rise for that matter. Probably this held true in days gone by when flights of ducks dropped into clearings by the hundreds & one could let a raft of them settle on the water & then start working on the ones still in the air & the others as they rose. This situation doesn't exist anymore. To me "Personally" the superior handling qualities of a SxS for the type of shooting I mainly do allows me to take the same amount of game with fewer shots. There is, I think, little question a .410 of the same grade & model, unless strictly speaking of "New Guns", will bring 2-3 times that of one in even a 20ga. Also, & not because I chose them, there is no doubt a 20ga or bigger is ballisticlly superior to a .410. I have no problem with anyone who enjoys it, using one, I just have no desire to do so. I also note virtually all the hunters I have ever been around who shot a .410 always opted for the 3" shell & Max loads. I can have just as much fun, at half the price on shells, with a minimum load in a 16 or 20 & for the same gun money shoot a much higher grade gun. Some of us, even on a high class board like this one, do stil have to watch how we spend our money.
