Seems to me that with Kenny doing the break in that it actually prevents anyone from getting a barrel that the manufacturer could say wasn't broken in properly. To me, him breaking them in really says how important to him it is as then there are no excuses for it not to shoot or be returned. He's suddenly bearing all the responsibility then. As I say, it's one man's opinion but he's sure offered up a lot more evidence than anyone else I've heard talk on the subject but then again, I haven't seen a lot of people talk on it. I went to the seminar a non-believer and left a believer and Kenny never got a nickle from me.....
