humm for us turkey hunters, moving from a 2 3/4 1 .5 oz load to an extra 1/4 oz produced a dincer center pattern more hits in the vital. So stuffing more shot in a 3 or 3.5 inch shell could delivery more vital hits in a old turkey bird.

But I have used every guage (except a 16) to kill turkeys and no matter what the size and load the birds are just as dead with a 1/2 oz load to a 3oz load.

Ps I don't own a 16 guage. Something I should correct.
