Yeah, but you're looking at powders with a max of around 22gr, right?

That means a 10% variance in powder lots could result in something like a theoretical 2.2gr variance, ALL ELSE EQUAL. So, if the one company gets the "hottest" batch and comes up with a max of 19.8gr and another company gets the "coldest" batch, they get 22gr.
The 22gr max company would suggest a starting load right around the max load of the other company.

That's with "all else equal", which it isn't. Personally, I'm a little surprised that small capacity handgun data doesn't vary MORE than it does. QuickLoad is a real eye opener. Variances of .005 can effect pressure DRASTICALLY.

The problem, as you so eloquently put it, is choice.
