i just skipped through the above posts trying to gather the pros and cons . some very good points made to say the least.
seeing that most turkey hunters are using 3'' or 3.5'' shells ,,,my first thought is recoil .a rifle scope generally has less eye relief than a shotgun / muzldr scope . now considering some of the positions we tree sitters get into when its time to roll the head of tom ,,this might just cause some serious greif. especially if you do not have a sling on your gun and you kill the bird . that means you'll have to carry the bird and gun in the same hand all the way back to the truck . the other hand will be holding that big knot,,,the one that is on your forehead , nose , eye or all.
my second thought is ,,,what if i don't make a killing shot and need a follow up shot? that gobs head ain't very big at all when he is running.
if i were to scope a shotgun for turkey hunting it would be one of the large diameter , long eye relief , red dot type . and it would have one of those little pad/buttons to press at killing time . the intensity of the red dot could be set at the truck , in the dark , and leave the main switch on all morning. but like somone else said already , that just adds more to think about and more things to go wrong with a mornings hunt ,,,and we don't have enough of them now to suit me .
