    Data 2200 powder

    I picked up a couple jugs of Accurate Data 2200 powder a while back, and have been trying to work up a .223 load with it.

    My understanding is that this powder, the old Data powder as opposed to the newer canister 2200, was a surplus powder. Anyone out there ever notice faster or slower lots with it?

    Working up a load, I'm using both a Rem 700 in .223 with a 24" barrel, and an AR 5.56 with a 16" barrel. I'm using 55fmj bullets. My chronograph seems to be accurate, as I've tested it with factory rounds that clock pretty much where I expected. The jugs were sealed, look and smell fine.

    The issue I'm having is it appears to be slower than expected. I'm going off the data on the jug label, and data for the newer 2200 (close to the same), but the measured velocity is significantly less, by at least 200 fps for the listed maximum. I even went over the listed maximum charge by a fair amount with absolutely no signs of excess pressure, even in the tight .223 chamber.

    I'm not terribly concerned about velocity, and accuracy seems good at this point, but this is a significant discrepancy from what I expected. Anyone else experience this sort of thing? If it's a normal variation with surplus powder I'll just continue my load development.

    Do you have this loading data?

    http://www.accuratepowder.com/wp-con.../04/DP2200.pdf

    I found velocities were pretty close, but never chronographed loads in the 222 or 223.
    Seemed to give me weird results in 7mm TCU, but not in the 6.5

    Mine is all OLD original batch of 2200.

    30 Herrett the velocity was spot on with the manual listing.

    It's been many years, but as I recall from my use of a small portion of an eight pounder velocities were well short of what the data indicated they should be.

    I've got a page or two of data somewhere in my files that was included with the powder when I brought it from Widners. Ill dig it out, if your interested.

    Yes, I have some of that data, but that sheet has more calibers listed. Thank you. I haven't tinkered with it any more yet, but will when I get time.

    Thank you, interesting to see that it's not just me. Honestly it really seems to behave like a slower burning powder. I went above max in a 223 chamber and velocity was rising, and no sign of pressure issues.

    My previous experience with surplus powders is that some lots burn quite different from others, and I'm wondering if I got a slow lot. I'm tempted to keep carefully working up a load, maybe in a couple other calibers as well for comparison sake, and see where it takes me. I'm not too concerned about maximum velocity, just want to understand what I have and find a good load.

    I would never do load development beyond published data with canister grade powder, so I was wondering if anyone else had seen burning-speed variations with this powder before. I even called Accurate but they weren't much help beyond saying that there could be more variation in the old surplus 2200 than the new commercial 2200.

    Yeah, I've seen surplus powders not match what previously listed data said it should do - I've seen it go both ways - slower and faster. Being your chronographing and watching for pressure signs (are you measuring the base of case expansion as well as looking at the primers) I'd watch for the plateau in speed and increasing pressure signs and not be too concerned about the data info you have found.

    No I haven't checked for case head expansion yet. I've never done that before at all actually, wasn't sure precisely how.

    I just found a good description from Hodgdon, think I'll give it a try: http://www.hodgdonreloading.com/relo...-rifle-reloads

    The only problem was that I didn't have any virgin brass, so I pulled down a box of cheap FC fmj ammo I had. I'm looking forward to carefully and scientifically trying it out the next time I get a chance. Thank you for the suggestion.

    I used lots of it making m193 clone never chronyed it. But shot way better than LC military ammo. Used it for 300m I was loading just below listed max in the listed data
