WMA 14 Brass question

[SHARPPOINT]

I have brass with head stamp WMA 14. I think its Winchester Nato? My question, everytime i run across a piece of it I will crush a primer when seating. I use a Dillon 550 with Federal SPP. I know Fed primers are the softest but i don't think thats the problem. I use brass from range pick up and the only time i have a primer seating problem it is a WMA... I've started sorting the WMA brass out. Anyone know why/what is the differnce with the WMA brass??

If it doesn't have the circle/cross on the head stamp, it ain't Nato ammo. S&B 9mm brass used to give me fits trying to put in a new primer so I don't use any foreign made brass in any caliber I load. Also some lesser known US brands, everything else gets culled.

Sounds like it has a crimp. If you chamfer the primer pocket it will work fine.

It does have the "circle/cross". Thanks for answers. It's not a big deal, have lots of 9mm brass. It just bugs me... Dolomite_supafly, I am thinking you are spot-on, just not worth the trouble.
Thanks

RCBS makes a military crimp remover for the case prep center it works great removes the crimp and puts a small bevel on the case allowing the primer to install as it is supposed to

I find a lot of military surplus brass is good, just remove the crimp and you should have some good brass. The stuff I use seems to last longer than commercial.

Yes most of it is thicker and annealed. With it being thicker it also has less case volume so be careful when approaching max because it usually takes less powder to achieve

Just stick your chamfer tool in the primer pocket and give er a twist. It isn't that much trouble, and only has to be done once per casing. Most military brass is good stuff.

Works for me. I bought a batch of once fired online. Had a few pieces of crimped pockets. Took a hand chamfer tool & got it right out. Can use a cordless drill also with the same chamfer tool w/o handle. Brass is as good as any afterward.
