Do you have Joe's 10 ga book?

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.

Joe Speroni aka BT Justice on this site and 10gagenut on the Refuge forum wrote a small manual for the 10 ga. 24 loads in total, half steel, half lead that he'd had the most luck with. Unfortunately, he died in December of 2019. His wife was selling his book for a while, but I'm not sure if she still is.

As I understand it, rsi wads are designed to blow their gas seal when a load is too far over pressure.

All of the loads I used came from the RSI manual. I could not get good patterns with them.

First, I'm just parroting what I've heard, so don't take this as established fact. I heard the wad was designed to blow the skirt as a safety feature, meaning, a turn skirt isn't necessarily a sign of poor quality.
But obviously it's a moot point if you can't get them to pattern well, right?

Myself, ive used only a few rsi wads (and mostly in 12 ga). They worked for me, but i haven't developed a strong opinion on them.
For that matter, I've only started scratching the 10 ga surface. Just as I started working it out, my two sons started hunting, and so I've spent the last year working out 20 ga loads (in between 2 moves and a new baby. Good grief...).
