I bought 1000 rounds of Sellier & Bellot 115gr 9mm from Brownells for $164.00 shipped, recently.
I shot 200 rounds of it through my PCR this morning without a single issue. Shot well, maybe a little less accurate than the WWB I usually use or I was having a subpar day. Either way it was a great range day for me. I now have 1240 rounds through my PCR with 3 ammo related issues. The WWB had 3 failures, 1 was a failure to fire, the primer had a good dimple but the round didn't fire. I tried it multiple times. I also had 2 WWB rounds that wouldn't chamber, I tried multiple times to chamber both rounds but neither did.
This thing is built like a tank.
I'm still waiting for the weather to cool off enough so I can carry my PCR
