American Reloading is offering a pull-down powder that is of interest. They call it 9mm Luger No.2. The naming convention tries to steer you towards thinking its for 9MM, but as you will see from some data, this can be used for MANY calibers successfully. Let me address some common concerns or questions relating to buying powder like this:
"Who manufactures this powder?" This is an OEM powder used by a major manufacturer of ammunition, even if you knew what manufacturer it came from, it would be of no use to you because OEM powders are not "exactly" like commercial powders you can buy.
"What is the burn rate of this powder, or where can I find it on burn rate chart?" To assist with this question, I will make a good judgement "guess" based on my testing and experience. This does not mean I am 100% correct, however, it is reasonable to assume my estimation is in the close ballpark. See below for chart.
"What commercial powder is 9mm Luger No. 2 like, so I can at least use solid reference load data to feel comfortable reloading it?" We have tested this against 3 commercial, popular powders close to its burn rate, and provided the data for you to view. Using this data, you can make determinations where you want to start your load process. This being said, NO load data on this website is official, or measured pressure, and should NOT be used without working UP from a more conservative, lower load. Differences in altitude, temperature and things like case capacity with different brands have a HUGE impact on pressure. So start low, and go up to your own comfort level, using your own judgement. If you cannot reload without having the exact bullet, exact case and exact load data from a manufacturer, such as Alliant, etc. Then I suggest you not buy this as you won't be able to sleep at night, or whatever. However, I love this, because this is not rocket science, and its not that hard to start low, and work up. Really.
"I have a Cartridge that is not listed in your testing, what do I do, will this work for my application?" Obviously, I only test a few calibers. Like 9MM and like 223. We cannot tell you what to do, and you should NOT take what we do and think its good for you. You need to make your OWN judgement. But here is how we do it, so you understand. Lets say you have load data for your cartridge for multiple powders. Lets use Accurate #2, Alliant Unique, and Ramshot Silhouette. Then you notice, that the testing data you see, is for a powder you never heard of, but its consistently showing performance between Alliant #2 and Alliant Unique, but its BARELY slower, and almost like Accurate #2. What we do, is look at another caliber, find load data for Accurate #2, then we start at the LOWEST charge for that, since we think this powder is similar. That is reasonable for us. We do this with Valkyrie using 223 data for example. Look at it another way. Look at the spectrum. In 9MM, for a 124 grain bullet, the fast burning powders, like Titegroup have max around ~3.9-4.1 grains depending on bullet. The slower 9MM powders have maximum for 124 grain bullet around ~6.0-6.2 (HS-6). So I know the range is 2 entire grains. Every bullet for every caliber has a range, from faster powders, to slower powders. If I think the powder I have is on the FASTER side, I start down under 3.9. If I think I have a slower powder, but don't know, I start under 3.9. You get it? You start under what you know is safe for faster powders, and work up....then you quickly learn what load data its "like". That is our method.
