Yet another 9mm powder

Where's the guy who used to always say "check the headspace", among other tidbits of priceless advice. (I've forgotten his CGN name) He'll settle this. :p
 
It's a bit of a nightmare to keep them straight but at least data exists. Got a couple pounds of Clays I picked up cheap because of people not wanting to sort it out.

Last powder shortage I found a 4lb jug Win AA Plus. Says on the side it's great for all sorts of shotgun and pistol loads but good luck finding any particulars. Was apparently discontinued after only 2-3 years. Works pretty good but it's a little nerve wracking creating your own data from a collection of vague clues.

Very similar to Hodgen Clays. Use Clays data or TiteGroup data.

Thanks Ganderite.
I did eventually find it on a burn rate chart and one or 2 loads and did some extrapolation and cross references to use it the way you suggest.

The burn charts don't give any numerical information but any reloader should look at one or two if the loads they're thinking of using don't look entirely right. It's one more point of information to be able to compare them to the loads listed for other powders nearby on the chart. Not definitive but let's you know if you are in the ballpark.
