I also view computer program output as "educated guesses.
Although I inquired about those four specific powders, will Quickload suggest others? Your point about expecting a velocity advantage from my 26" barrel was something that occurred to me also. Maybe a slightly slower burning rate than the powders I asked about would help? Maybe Reloder 15, Varget, N540, or H380 (all of which I already have)??
I really appreciate you taking time to consider my questions.
