I've been loading 10 ga steel since 1990 and I still have over 100# of it. I'm "late" in my waterfowling career and I don't really want to spring for bismuth or tungsten. I'm loading 40 gr of Alliant Steel, BP TPS wads, and 1 1/2oz of BBB in the Federal hulls. I'm also shooting 1 3/8 oz loads in the Rem hulls with 44.5 gr of Alliant steel, Fed 209A primers, BP TPS wads with a 20 ga fiber wad inside, and 16 gr of buffer with steel BBBs. This load runs between 1450 and 1475 fps per my chronograph. I also run 1 1/4 oz of buffered BBBs in a Federal hull, 48 gr of Alliant Steel, F209As and the TPS wad. Surprisingly, or maybe not, the 1 1/4 oz load gives me roughly the same number of pellets in a 30" circle at 60 yards through my Terror .720 choke. By the way, the 1 3/8 oz load in the Rem hull with #3 steel is an absolute mallard chrusher (no buffer). I don't have "Joe's 10 ga book". Never heard of it until joining this forum recently.
