If anyone is interested in an intellegent discussion regarding this topic I'd like to offer my opinion on it. But I'm not if all I get is an argument. I'm a firm believer in barrel harmonics and how they affect accuracy, and how to manipulate a load to take the best advantage of the physics involved....in any good/decent/real good and decentquality barrel.

The audette ladder system has been mentioned...it's along those lines.
