Yeah, they all shot left (testing at 70 yds).  That would be left of bore sighting per se.
The Kleenbore was really inconsistent as well RE velocity.  Not sure about powder dried out but the bullets had bimetallic bonded to the case.  I tried to pull some with Hornady collet puller.  Damn difficult.  Some wouldn't even pull.  Just tried a few.  A shame though, I was given 4 boxes.
