S.D, they, 12 Gauge 3.5 megadeath howitzers, ought to be. That's why they kick so darn much.
At this point, I've yet to need the extra payload of the longest shell. Even the 3" loads here are restricted to Waterfowl (Hevishot 2s) and Turkey( divers loads of 4s, 5s and 6s, up to 1 7/8 oz).Yes, those turkey loads do kick from a sub 7 lb gun. But I do not fire off a lot of them in a day, even when bench testing and patterning.
But then, I'm only 63.....
