reloading priming question

[jaymark6655]

I think the F C stands for Federal Cartridge, but I am not 100% on that.

Thanks guys, but it was AWS's idea to deburr the pocket.

The upper two cases with the FC marking are definately NATO/Military cases and would have a crimp unless someone swaged the crimp out already.

They make a swaging tool for the primer pockets.

 

Looks like I'll have to watch that with this brass.. about the thicker walls and smaller webs.

Good thing I wasn't planning on using them for anything other than plinking and minimal grain loads.
Actually I have a few un-reloaded rounds left. (I thought the neck had too many stretch marks) so Ill use them for my test subjects.

Also found a trick about using a paper clip to feel for a dent for headcase separation. Ill keep an eye on this round of brass very closely.

Anyone know some good brass that really lasts through many rounds of reloads?

I've had good luck with Win. Brass(others cuss it) i shoot in my 223 and the neck it up for my 6x45 and it has held up very well for me.  I use it for my accuracy loads/target loads.

The ring around the primer pocket is a sure sign of a crimped primer pocket.  If you can compare with a Rem or Win primer pocket.  Just looked at some brass I have here, Military brass head stamped TW(Twin City ordinance Anoka, MN) and LC(Lake City munitions plant Minneapolis, MN)  have crimped primers, civilian ammo FC(Federal Cartridge) and PMC(marked 223 Rem) have crimped primers, civilian ammo by Win and Rem(marked 223) do not have crimped primers) that's all I have laying around.
