This year i been using 1 5/8 bb in a fed hull doin 1450 wasn't really impressed but i use itx as well in 1 1/2 oz rem hull it crushes geese in the 10 ga ,with either hull i rarely get more than a couple of reloads with the gold 10.I like the rsi 1`1/2 oz in the rem hull i think it uses 47 gr of steel.Personally i think bbb is the way to go with steel it retains a little more energy out to 60yds.Ive had problems with both hulls seperating at the base or stretching the hull .I think what ya got are pretty good reloads if ya can get some rsi wads try them to compare against bp
