Re: Can anyone ID this powder?
<div class="ubbcode-block"><div class="ubbcode-header">Originally Posted By: ChadTRG42</div><div class="ubbcode-body">It's never a good idea to try and figure out what powder they use. But I can tell you it's NOT H4895, Varget, XBR, or one of the Hodgdon extreme powders. It could be IMR4895 or R-15. IMR 4895 is going to be longer than R-15, so it's hard to tell in the picture the length of the kernels. But FGMM uses several different varieties of powders. The best option is to work up a load in YOUR rifle that shoots well. I've never understood why someone wants to try and duplicate a factory load, when you can reload much better ammo. </div></div>
I second this. It doesn't matter what powder the large manufacturers use. If you could get it, you'd have to buy it in 30-45lb kegs, and pay a $1,000 freight fee per shipment. The non-canister powders usually vary much more from lot to lot than what is available to most reloaders, requiring a workup for every new lot of powder.
If it were H4895 or XBR, 43.3 would be over max, by quite a bit. I would guess that Federal now uses Alliant powders, as they are both part of ATK. A non canister variant of RL15 makes the most sense, as that is what it looks like, and is the most appropriate powder made by their sister company. But, the charge weight should not be used as template for your own loads.
