The PMC .223, IIRC, has crimped primer pockets...so expect to spend some extra time dealing with that when you go to reload.
As common as .223 brass is, I usually just avoid 'em.
The Wolf is good plinking ammo. The price looks decent--it's selling for $4.00-$4.50 per 20 locally. I sold all my x39's just after the Wolf Military Classic came out...but the old black box stuff wasn't too bad. A little dirty, but always reliable for me.
Shipping sure hurts, eh?
