    I am still brand new at reloading. Ive tried 3 attempts at this so far. Load 1 was 5.56 case, rem primer, win 55 gr fmj, 23.8 gr imr4064.
    Load 2 5.56 case, rem primer, win 55 gr fmj, 24.5 gr imr 4064
    Load 3 5.56 case, rem primer, win 55 gr fmj, 24.2 gr imr 4064.
    This is the best group so far at 25 yds (Load 3)

    I thought maybe I lost my ability to shoot so I tried 5 shots at 25 yds with some surplus 5.56 and got this.

    What do I need to do with my load.

    if you cant see the pics the reload gave about a 1 1/2" group
    the surplus gave me 5 shots in 1 large ragged hole probably less than 1/2"

    I don't know. I'm getting decent accuracy using Armscor 55 grain FMJ's and 25.2 grains of H4895. CCI SR primers.

    I recently read somewhere that changing from one powder to another can sometimes mean that the gun doesn't shoot well for the first several shots unless you clean it between powder types. It was explained by saying some of the powder residue from the first type may interact with the burning of the second type. The author said his guns usually settled down after 5 or 10 shots.

    I dont know what action you have,what twist, and barrel length and whether metering or weighing loads. As to what I have seen the 20" AR,s with 1in9"twist and faster give much better performance with medium fast burn rate like !MR 4198,AA 2230,AA2015,up to IMR 4895. than with the medium burn rate like IMR 4064 which is an exelent powder in longer barrels with slower twist which gives more fps with lighter loads.(Sierra,using a 20" barrel in 1in7" twist and a hot load of 25.8gr,s of IMR 4064 gives 2800fps.Their load for a bolt type using a 24"barrel and 1in14" twist is (hot load)26gr,s of IMR 4064 at 3200fps,or 400 fps faster leading me to think IMR 4064 and similar powders perform well in longer barrels and slower twist rate.I also recommend staying away from extruded powders in small capacity casings and weighing each load if you use them.I personally use AA 2230 in all aplications of .223 and even tho there might be something better for some loads 2230 is satisfactory for all I have tried. sam.

    Sam, thanks for replying. I am using a Bushmaster M4 14 1/2" barrel 1in9 twist. I am weighing each load. From what you wrote it sounds like this is the wrong gun for this powder. short barrel and fast twist rate.

    Is extruded powder the same as stick powder? Is AA2230 a ball powder? And why use ball and not stick? I am trying to learn as much as possible about reloading. I want to be safe and accurate as possible.
    Thanks again, Johnny

    Yes,extruded is stick. AA2230 is ball,flake powder.they smash them to change burn rate.For your short barrel I would think AA 2015BR would have advantages.It is a small grain extruded powder and I hear it meters well.My experience with short barrels is in handguns but it works great in the contender as does the AA 2230.I find Benchmark and H335 tops in 15" barrels on contender,s. Others on here have experience with short barrel AR,s and I am sure they will get right in here.The more opinions the better,but try to verify any info posted on here including mine.If you have trouble looking it up let us know. sam.

    the 4064 might be a tad too slow for consistent chambering of your next round too.
    i would look at the 2230 or h-322 even 4895 should work.
    the winchester bullets you are using are not the most accurate either.
    like sam said: take a step back, investigate what is being used by other in the ar's
    and try what you are seeing them do.
