Just back from Argentina, I use a cloth bandaid on my loading thumb and wear them out at each shoot. Had to go to duct tape the last day but my thumb was not cut in spite of my 390's best efforts. I am to old to do the high volume dove bit but I did manage to shoot 1700 shells in 8 hunts, ducks, dove and pidgen. Seir gave me credit for the shells I did not shoot.
