I went threw 8 jugs last year in my knight extreemes. When I was done I decided that it didn't shoot any better than t7. I got a pair of lehigh Gen II breech plug's a month ago and thought I'd give it another go. Out of these guns with the lehigh plug, BH is outstanding. Shoots very well, no swabbing between shots, clean up is a breeze, yep in these guns with the way they are set up it is worth what it cost. Oh did I mention clover leafs all day long unless I mess up.
