I've read plenty of times that Wolf ammo has a habit getting stuck in the chamber of AR-15s.
I've read countless times that you should always bring a cleaning rod to the range.
I knew these things, but I guess I thought it could never happen to me.
About half an hour ago, I fired about 40 rounds and the last one failed to extract. Now I get to wait until I go home tonight before I can fully clear the weapon.
Boy do I feel stupid.
