RE: 410 single shot
Although it can be done,if you have access to a heavier shooting gun than I would suggest taking that route.With that said by all means DO NOT take a gun you have not shot to the turkey woods.
If you are hell bent on shooting a 410,than I would suggest looking at purchasing a box of Remington Express longrange field loads.They manufacture a 3' 410 load that shoots almost an ounce of shot.The fps is not very fast so I would suggest going with 4's for some knockdown power AND ABOVE ALL not taking any shots over 20 to 25 yards....good luck
