BE86 is the latest version of bulls eye that has a flash suppression feature.
4.5 grains works great in a 9mm load using 124 grain Boyne cast projectiles.

Just compare(time) it to a powder in good condition to give you some idea of its burn rate.
There is a similar test in the industry but I don't remember the details.

It's too valuable to waste, and the chronograph will give me a more accurate idea I think. If the book says a 3.5gn charge should make 814fps out of the 686, and I see 780fps I'll consider the powder to be good. If I see 650fps I might have to consider it suspect, in which case I'll keep it myself and use it for Cowboy loads.

The object of the test to get an indication if its more or less burning at its correct rate. If due to age its waaay too fast then even a moderate charge could be dangerous.
Its only a few grains.

I've seen that before but I'd rather burn it down the barrel
I'll chrono some and compare to Alliant's data.
