Is this brass still good?????

[kharlingca]

Need some help from veteran reloaders, I have been reloading for a short time now and while inspecting some.223 brass I noticed a grooved ring around the top of the neck. I believe that this is from a military crimp, but I am not sure.

Can anyone tell me what this groove is from and if it is safe to reload, I have looked for answers in a couple of books but haven’t found anything.

Thanks

Yes this mark is a crimping mark. Just resize and trim and do not bother with it. It is safe to use and shoot. Just as a side note, never try to crimp a bullet that have no cannelure. This being said,crimping is not necessary even when used in AR platform.

Looks like a .223 round.
It is from the military crimp (Meant for full auto and loaded usually to higher pressure/velocities) and is safe to reload. Should you see cracks develop at that area, discard those cases.

I didn't know that. I thought AR's required the crimp. Thanks for the info too.

Debur it and check it dimensional with either go no go tools (i.e. case checkers) or a good set of verniers, micrometers (dial or digital).
Military spec ammo is general a tight tolerance manufacture SPC. Thicker walls, heavier projectile crimps and Primer crimps not generally used in commercial ammunition.
When in doubt throw it out, from the reload bucket into recycle one that is.
There lots of books and information on net and lots of experts here so don’t ever fear asking for help and most will be happy to get you safely going.
