They haven't taken them off their Web-site and also have no point out of these staying discontinued on web-site? Where you listen to this? I googled it and only matter that comes up is this post?
If we might have integrated powders like Alliant Reloader and Some others, which are infamous for big swings with temperature … you'll see much bigger numbers on this graph.
