as will be all too common, the skill and experience of the person using the equipment has a huge effect on how effective it will be,
Ive used both an Ithaca 10 ga mag 10, and an benelli black eagle 12 ga 3" semi auto on dozens of hunts
the benelli has interchangeable chokes, its lighter and ammos cheaper
if you do your job as a hunter correctly either choice in shotguns works just fine,
but theres zero doubt the 10 ga throws a bit tighter /denser pattern and has measurably increased reach,
now that rarely is a huge factor, as I try very hard to get turkey into the 35-40 yard,max range before you fire,
yes the 10 ga is a larger gun and heavier and ammos at times harder to find,
but its not like you shoot several boxes of shells on a turkey hunt
I generally have a box of shells last a couple years.
so why would anyone want a 10 ga?
if youve ever had a turkey strutting around at 45-47 yards, and were reluctant
to risk wounding ,you know damn well the the reason,
and yeah its damn effective even at that range, and probably a lot further,
but I refuse to try stretching it past that.
having confidence in your equipment, and a well proven effective pattern, does mater.
theres also the shot size options, lots of the guys I hunt with use #2 shot in 2.25 oz 10 ga hand loads
and that will kill very well at 50 yards and probably a lot further,
btw I know from experience that both the powder charge and shot cup design DO have a noticeable effect on the shot pattern density
BLUE DOT POWDER and the ballistic products longer shot cups with the fed cases and 2.25 oz #2 shot is what Ive used on many hunts
IM NOT impressed with the MEC loader I use but it does work
