Do to the recent shortage of handloading components, I was unable to purchace H110 powder for my upcoming 44 magnum loads. The only thing I could find was Alliant Powder's Power Pro 300-Mp. Its a magnum handgun spherical powder that the attendant said would work well for the 44 mag.

What do you all think?

Another winner from Alliant. Impressive results from what I have seen.

The cool thing about 300MP is you don't need magnum primers..

Do magnum primers work better? From what I hear this stuff has quite the muzzle flash compared to h110, so I would have thought magnum primers would be required. Even more so considering the bottle says it is a specific magnum gun powder. :confused:

Nope.. I know it's counter intuitive, but this is some pretty amazing stuff.. Alliant tested and recommends standard primers.
Yes, it is flashy, in shorter barrels and has quite a bark to it, but it’s a high performance magnum handgun powder, so when hunting, the primary purpose I think, it doesn’t matter.

I did some work with .357 Mag also and found standard primers will work as advertised with 300-MP;

I use Alliant powder for nearly everything these days. My only 2 exceptions are TAC for 223 loads and Silhoutte for 38spl +P and 45acp +P loads, as that powder is low flash and nice for duplicating SD factory cartridges.

I will probably rejoin Load Data this weekend, and if so, I will post his load data. Really like that Brian Pearce.

Magnum primers

I don't believe Alliant recommends magnum primers for ANY of its pistol powders. At least they didn't used to. I had some really freaky things happen using 550 primers with Unique. Young and stupid.
