I have no idea who he is other than reading his website and reading about his barrels on 6mmbr.com. If someone wants a broughton barrel he can have one. If someone wants a Lilja he can have one, same for a Douglas or krieger or McMillan or Snerdly Snoids...and if Gale McMillan says dont break them in and your particular barrel woobie says break 'em in, then you can toss netshoes at each other till they are blue in the face, that debate has been going on since the net came into existence and before then
But there is no such thing as a Blaser barrel that doesnt shoot submoa, and guess what, Steyrs too. Niether need break in, espcially the hammer forged chamber calibers (and remember what barrle break in is for). Maybe you should try a more interesting debate, such as hammer forging over button rifling, or explain to us why a premium barrel maker would not hand lap it before it leaves his shop, or PO Ackleys views on lapping..... even better.
