Oh, I hear ya. I went at that W-W 9mm brass with a mind toward MAKING IT WORK, come h--l or high water. I tried every make of primer I could find locally--Fed 100, Rem SP, CCI 500, WSP. I reamed the pocket edges with a counter-sink in a drill motor. I used the RCBS primer pocket swager (meant for de-crimping mil-spec brass). No love whatsoever. I was ON A MISSION. And......EPIC FAIL.
Remington 9mm has behaved well for me in my pistols. Other folks' tools, or guns, or skill sets might be able to make that W-W brass work for them, but it was beyond me.
