Found 5 boxes of Remington Premier Hevi-Shot magnum turkey loads 10 ga. 3 1/2" 1225 Vel. 1 7/8 oz of shot #6 shot.. You think they will pattern good with that .680 choke
They pattern good enough out to 50yards in by BPS with a PG.680....
Average 160 to 180 hits in a 10" circle at 40 yards in mine....
They pattern and kill birds as good or better than any lead shells
I've used over the years...
