I had purchased a can of AA#9 a few years ago and its been sitting on the shelf for a while, not sure what to use it in. I originally bought it for 357 Mag, but I've stuck with 2400 & 296 in it.

So, I looked up what other calibers it was suitable for, and found data for 30 Carbine. Thought I would give it a try. Man, glad I did. I really like it MORE than 296. It meters just as well, but seems to give lower ES. Surprisingly, it also gave pretty high velocities. I'm not looking to beat up my rifle, but would like to be around 1900fps.

Accuracy was the same or better. Below is some of my test data using Rainier plated RN and some Remington SP.
I think I will settle on 12.2gr with the Rainier (1920 fps) and 12.4 gr with the Remingtons for approx 1900 fps. I think the Remingtons go slower because the bullets are undersized and measure .3065".

Max loads seem to be 12.8gr - 13.1gr, depending on the data you use.

I haven't used it but I recently tried Lil Gun with good results. It's a lower pressure powder with higher velocities.

I have used some LilGun in my 300 Blackout, but it generates a lot of heat. Probably nothing to worry about in a rifle, but still....
Maybe I'll burn it up in the carbine too, don't want to use it in my revolvers. Others I prefer more.

If you like 2400, W296/H110 and AA#9 in the 30 Carbine you will just love Power Pro 300-MP. Unfortunately there is no data on the Alliant site for 300-MP in the 30 Carbine but if you contact them and ask for the data they will supply it.

Luckily any Magnum class handgun powder will work well in the 30 Carbine, some better than the others. Since every rifle is different and there are so many available powders I'm sure you can find the combination that will work best in your rifle. Off the top of my head I can count at least a dozen powders that will deliver top performance in the 30 Carbine.
