I'm on the last few hundred rounds of 2,000 rounds of WPA. I never really got any stuck cases, which is the biggest issue with steel cased ammo in ARs, and I got lots of them with other steel cased ammo. Even when I got my carbine very hot, like doing multiple mag dumps, I can't recall a single stuck case. I've actually had more stuck cases with brass cased PRVI 62 grain. I did get a few failures to fire, including one that cost me a second or 2 during a v-tac 1-5 drill portion of a match stage.
And it is pretty dirty, although I'm not super anal about a clean gun, so it's not big deal. I did clean out my chamber with a brush and a mop after every time I shot it.
My carbine is a 16 inch barrel 1/7 twist with a carbine length system and a H buffer in case anyone was wondering.
Accuracy from the WPA ammo was good enough to hit a half size steel silhouette out to about 200 meters from sitting.
I plan on buying another 2,000 rounds eventually, once I burn through the last of this I'm going to run my AK for a while. [url=http://yoursmiles.org/p-m
