That is good info Big Eddy. Buddy texted me his Lyman page from 25 years ago --
For those that may search this thread one day: Those Lyman numbers give me some confidence that 16 is fine in a lever gun for sure and I'll see if they stick in the cylinder of my SA. If they do not, that will be it, that is as hot as I'll go in deference to the caution in other books. The new powders are a little different than the old. Lawyers and test methods also change a bit. Sometimes, as with Speer and Nosler, you get very different data. Go get more dataI now have good confidence 16.0 will be fine. If the powder REALLY changed a lot, it would have a new name. I feed several .357s in the family, don't want any to have a problem. If it shoots tighter than Unique I may switch for hunting, H110 throws awesome. The Hodgdon web powder page is probably the truest number you can find with all the variables but since I am throwing with a 650, I want some margin at the top end, I'm pretty sure I have that despite some more conservative numbers in other books. Like potato chips, if you have a 650 set up, a test run is going to be 100 rounds.... it just is. If the 16s stick in the SA cylinder, I'll be back and update this thread, but I'm not expecting it. I find flattened primer peering pure VooDoo, YMMV.
Now to fine time to empty them...
Final note, H110 is suspected of having a detonation/pressure spike when loaded below book. It is the one powder I would not load at min or below book for any reason. This is the internet. I'm really not sure if that is true but the general consensus I have gathered.

Heavy loads wear out guns, light loads blow them up. Be careful out there.
