    Yes. It is far less than optimum for .223; but provides a means of shooting the .223/5.56 (and other small bores) when more suitable powder becomes difficult to acquire as has occurred at least three times in my lifespan.

    Currently there seems to be a good supply of powders tailored to the .223/5/56 (although at a much higher cost than a few years ago) such as:

    H322®
    Benchmark
    IMR 8208 XBR
    CFE 223
    Varget®
    Winchester 748
    BL-C(2)
    H335
    IMR 4198
    H322®
    H4895
    CFE 223
    Varget®
    IMR 4895
    IMR 8208
    XBR
    BL-C(2)

    I continue to have a goodly amount 860, 870, and 872 powders that I use in my AR-50. Should the current legislative activity against the 2nd Amendment (House, Senate, and even President sounding off on Gun related legislation; as well as Wal-Mart and other companies "Getting out of the Firearm Business partially or entirely", there could be another round of powder shortages. Hopefully these pages will provide the incentive and a foundation of "Home Based Research" that can support others in their continuation of the shooting sports.

    After reading of Mustang's experiments several years ago, I tried some 860 over a 4227 kicker. It is now my favorite load with RCBS powder coated bullets in an AR15. I found that while GCed bullets shot best, unGCed were not far behind. Certainly good enough to be used in practical situations.

    That's good to know, maybe you'd like to share load specifics, velocity?

    swheeler,

    The firearm is a S&W M&P. It is stock, except for the iron sights being removed and replaced with a 4x scope or a red dot. Twist is 1-7 I believe. The bullet is the RCBS 55 grain cast out of 3ww-1lino alloy and sized .255.

    The load I settled on is 20 grains of W860 over 5 grains of IMR4227. I mostly use magnum small rifle primers, but other primers will work almost as good. I started load development with 3 grains of 4227 and then filling the case with 860. Result was a dirty action and barrel, action would not cycle, and accuracy was poor. I then began increasing the 4227 and decreasing the W860. I finally settled on my load which is pretty clean, cycles the action for many rounds without jamming and shoots 2" to 2.5" five shot groups at a hundred yards off of sandbags with GCs. With no GCs, the groups run 3" to 3.5". Velocity is in the low 2200 fps. For comparison, mil-spec FMJ loads group a 1.5". Good commercial jacket bullets would still not group at an inch.

    I worked this load up in the days when it was hard to find components. I now have a Lee six cavity mold that works almost as good as the RCBS. I have LOTS of brass and powder. I have a fair amount of primers. I found that all the small primers could be made to work, magnum rifle to standard pistol. Primers are the weak link, can't have too many.

    I have had occasions to let several people who, for various reasons, have had little or no chance to shoot a firearm, and no chance to shoot an AR15, fire this rifle with a red dot mounted. Standing, shooting at 5" plastic target balls at 25 to 50 yards, then at rocks on the hillside to as far as they can imagine, they have all loved shooting this rifle. All left dreaming of having, or at least being allowed to have, such a weapon.
