Jordan Smith and Mule Deer (JB) have touted DBC as being a revolutionary godsend for many years.......I have tried it in several rifles. A couple it worked very well in, a couple it worked with limited success, a couple there was no improvement at all.
Try it but keep an open mind, might not be the miracle that you are looking for
You are being more than a bit hyperbolic here.
If you can quote a post from either saying "revolutionary godsend" I will be shocked.
DBC does work but it won't fix all ills that can afflict a barrel.
I have put it in many many good barrels and it's always made them a bit better.
