I have been struggling with a Shilen barrel.  It is an 8 tw, 26" st stl var/tar. I have about 1200 through it.  Accuracy is inconsistent, and it fouls quickly now.  Most recently, gave it a thorough cleaning with Bore Tech Eliminator then JB.  After 26 rounds it was copper fouled. again. I dont know what else to try.  I expected longer life.
