Steve,
I have not had occasion to play with non-tox in the .410. I can give some distilled info concerning my testing of 3" Pb loads.
If I want fast and tight (well, at least 9/16 oz of the full payload in the effective pattern) I use RPs. They ran 1270 fps, way over spec. They feel like it, too. Frankly, I don't know how they do it......maybe I don't want to know. My full '42 puts over 65% inside just 20" at 40 yds in #6. In #7.5 through mod it hammers phez to my self-imposed 25 yd limit.
If you want relatively open and even, and don't fret over pedestrian 1120 fps velocities, you might like WW's loads. Very soft recoil. I've used this for early Oct WC and grouse.
The Fio 3" I tested was interesting. Wad is basically a gas check. It had no petals at all. Chrono'd 1230 fps.
The B&P 3" is the only Pb loading I've seen with full-length shotcup petals. Not surprisingly, it shows the least pellet attrition on paper. IIRC, chrono said about 1180 fps. Throws a larger, more open effective pattern than the RP. Not much field experience with it yet, but I'm thinking grouse/WC.
