    Remember the “.224 55 GR. FULL METAL JACKET BOAT TAIL BULLETS FEDERAL XM193” bullets that RMR sold a while back, that wouldn’t feed well through a bullet feeder but did have the virtue of being cheap for the time? Couple thoughts on that:

    1. I would say they are OK but finicky in a bullet feeder. I’ve noticed issues with them getting stacked up near the top of tube on my MrBF if I somehow drop too many in there. If that doesn’t happen, they seem to be OK.
    2. I put 26.5gr of TAC behind them and load them to the cannelure. No ill effects yet. Haven’t run a chrono on them, but will update this post when I do. This is probably somewhere just above .223 pressures, but below top end for 5.56 (according to the Western Powders data, anyways). I’ve loaded it as hot as 27.2gr and seen nothing particularly interesting from the brass, so I think 26.5gr gives me some safety for how I load (which is on a progressive).
    3. No particular accuracy issues, but I don’t shoot for groups.

    I have a couple 8 pound kegs of Military Surplus WC 844, which (I have been told) was originally used to load military 5.56×45 M193 ammo. Since there is VERY LITTLE DATA available for Milsurp powders, I thought it might benefit someone to post my chronograph results for Hornady 55 gr. FMJ BT bullets.

    Keep in mind, the fact that Milsurp powders can vary significantly from lot to lot, so start low and work up! You are on your own if you decide to use this data!

    25.18 grains WC 844, 55 gr. FMJ BT, 2755 fps AVG, 12 fps SD, from my AR with BA 16″ SS barrel 2.217″ OAL

    25.83 grains WC 844, 55 gr. FMJ BT, 2859 fps AVG, 27 fps SD, from my AR with BA 16″ SS barrel 2.217″ OAL

    27.10 grains WC 844, 55 gr. FMJ BT, 3028 fps AVG, 22 fps SD, from my AR with BA 16″ SS barrel 2.217″ OAL (this load was slightly flattening my CCI 400 primers… I didn’t go any hotter, and accuracy was better with the slower loads.)

    I didn’t buy my WC-844 here, but I found some available for sale NOW at this dealer (no experience with this seller…)

    WC-844 Powder for sale

    Note: $208 for 16 pounds ($13 per pound!) makes this very interesting, if you load a lot of this type of powder. My WC 844 has been very accurate!

    Looks like the powder I linked to above is a SCAM!
