View Full Version : Anybody use IMR 3031?
November 13, 2006, 10:05
Does anybody use IMR 3031 to reload .223 and .308? I'll be shooting 55gr and 150gr bullets, respectively. Lyman does list this powder for these two calibers but I wanted to see if anyone had any real world experience. I want to reload both these cartridges but want to limit the different kinds of powder I will need to buy.

I have used it with published data - it is a good choice for carbines - I use it a lot with 30-06 in a carbine - best I have found for velocity and low flash with a shorter barrel.
If you are not working with short barrels I would suggest moving to Varget.

The very 1st rounds I loaded used this powder. Its a fine powder thats been around since before WWII.
Its a stick powder so it has the inherent variations that they have when using a Uniflow type powder measure, so I have pretty much gravitated to ball powders.
The only stick power I use is the original 4895 for 30-06 so that I will have the correct burn rate for the gas operation in my Garand.

buy varget, it works great in 223 and 308.
high velocities too.
26.5 in a 223, will work great.
47.0 in a 308 with a 150 is listed as max for just over 2900 fps.
fastest load listed in the hodgdon powder loading info....

To answer your question, yes I've used it. In fact, I've gotten some great performance out of 7.62 rounds loaded w/Fed match primers and GI match brass, 39.5 gr of the powder & a 168gr Sierra MatchKing. Use at your own risk, yada yada yada.
This is one of the best performing powders I've found, but I've also found that I prefer loading w/TAC. It meters like fine sand, and you can load 5.56 and 7.62 with it easily. My only two complaints about 3031 are that it's not a more modern, temperature-stable powder like TAC or Vitavhoi (spelling?), and it's a stick powder so it doesn't meter easily in a powder measure.
If you've got an electronic powder scale, or a lot of time to weigh each charge, go for it.
Hope this helps.
