I have a White .12 ga. Thunder shotgun and use it right now for squirrels. I have a Xfull choke in it and shoot them out to 30-40yds. I just bought a Hastings turkey choke for it,but haven't tried it out yet.
My small game load is 75 gr. T72Fg, White shotcup, 1 1/4oz. #6 magnum shot. It's a hoot to shoot them!! Got my limit (6) last several times I've been out with it.
These were taken couple years ago. (date on pic is not corrrect)
