    Getting ready to reload my first .223 in a couple of weeks. Have reloaded 10 each of 45 AUTO and 380 AUTO but have not fired them yet - hope to test them this week.

    I have a Colt M4 with a 1-7 twist. I have some Hornady #22492 52 gr A-Max and noticed that on the box they show a twist rate of 1-14. Are there going to be any issues using that bullet in my M4?

    Thanks.

    Shouldn't be a problem. A-Max's should be constructed stout enough to handle a 1:7 twist. Some of the lightly constructed "hornet" bullets could come apart in flight due to the high spin rate.

    +1

    Hornet, SX, Blitz, and other lightly jacketed varmint bullets may blow up in flight from a 1/7 barrel.

    The A-Max will not.

    Yep - Dogtown's should be OK as well.

    Dog towns might be a little fragile for the 1-7 twist. Don't really know till you shoot a few. If you have multiple holes in the target for each round fired, they are too fragile.

    Choot'm and see.

    If you notice a Grey vapor trail halfway to the target?
    Didn't work.

    If you notice a 1 MOA 5-shot group?
    Did work.
