223 1-7 twist vs. 1-14 twist

[emptybrass]

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.

Good news. I also have box of Midway Dogtown Bullets 55 gr FBHP - will they be OK as well?

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.
