I e-mailed Alliant yesterday and got an immediate answer. I wanted to know when nitrochemie's magnum version was coming out and what it would be named. The answer: they are going to be offering 5 new powders. They will be called the Power Pro series. The first two entries will be out in the next few months. One is called Pro 3000 MP for magnum pistols. The second one is called Pro 4000 MR for magnum rifles. ---------------Graf and Sons has a listing for Pro 4000 MR https://www.grafs.com/product/245404 It is not in stock yet but they are taking orders. Nice to be first for once. -----------------It may be a bit late for this fall's hunting season. If it adds velocity like RL-17 it should be very interesting to see what it does with magnums.
