It is a rifle powder intended for reduced loads. Very bulky. I have never used it in .30 Carbine though. It should work just fine though. About the right burn rate.

I have never used this powder, but I did find it listed in my current Speer Manual for use with the 30 Carbine. However the maximum load with this powder and a 110 gr FMJ bullet is only 1631 fps ,one of the slowest velocities listed. Most of the recommended powders show velocities over 1900+ fps. I would select another powder like WW 296, 2400, or AA #9. The slower pistol powders work best with the 30 Carbine.

yes....i saw that about the velocity also but if its still being listed in etc. i believe it is also a compressed load, 11g ? not that a light load is needed in the carbine but could you call this a "plinker" load? i had intended the sr in a bolt using reduced loads, then i saw it listed for the carbine. was just curious.

I would call it too bulky a powder, not a light load.

I think they ran out of room before the velocity got up where it would be with the other "usual suspect" .30 carbine powders.

Hodgdon shows 11.0 compressed with a 110 bullet giving 1,545 FPS at 26,100 CUP.
About 10,000 PSI less then H110, and almost 600 FPS slower.

If your carbine will cycle with that much less gas pressure, I suppose it would work though.

I use a lot of it for reduced loads with jacketed bullets. Great results, nice bulky powder so less chance of a double charge.
Never used it for 30 carbine, though.

11.0 Grs SR 4759 in an unsized .30 Carbine case. Just enough room left for the bullet. The powder is not going to compress much.
