Last year in Missouri there 450,00 tags sold - I doubt if there's 450,00 using doubles in the wide world today.
Ducks Unlimited did a survey a few years ago of guns used for ducks and geese and SxS's were a paltry 2%. When Destry "Market Hunter" Hoffard and I shot ducks in LA pre-Katrina with our Parkers we might as well have been shooting flintlocks--the locals were amazed that such things still exist; some had never seen one.
Suffice it to say that we doublegunners were held somewhat in awe to our faces, but probably laughed at behind our backs. After all, the way these good ol' boys keep their 870's clean is to sprinkle some sand in the bed of their pickup truck and let the uncased gun slip and slide all the way home after a day's hunt. Yet even handicapped with our Parkers, it was all opportunity, and we never but once failed to shoot our 6 bird daily limit. EDM
