my buddy got in some winchester supreme #4 2-1/4oz
Setup:
Browning BPS 10
Kicks 690
At a measured 36 yards ( was at his house and was about the longest shot we had)
Put 2 shots down the tube and came up with somewhere in the area of 130s+ one shot surpassed 140 easy. I knew my gun patterned the 4s better than 5s I just picked the 2oz 5s over the 2oz 4s but i think i may hoard up a few boxes of these shells. Man i wish i could find them in a 5 shot
