Last year H13 #7 has B&P wad this year I am not sure but I cut one open and it is definitely different. Anyway out of my gun, 870SM, the 3.5" #7 shot near 300 with pure gold 670 with old H13. New H13 around 250. Still good but wondering if anyone has gone thru the whole patterning game with the new stuff and found out if it likes more open chokes or tighter chokes as a rule.
