I own 4 CFW barrels. But the one contact I solicited information from, has clients numbering in the 1000s. Realize, you don't make friends bashing a barrel manufacturer. So that these guys speak at all, is quite remarkable! It's like asking your doctor an opinion about another doctor. Silence is common, unless they only have superlatives.
My contact is slightly thumbs down on CFW. The odds are in your favor of getting a CFW barrel that will shoot. But the odds they may be fussy during load development are higher. And they may not shoot well no matter how many bullets tried, and effort expended. I'm leary of CFW barrels for the time being. Don't really plan to purchase any more at this time. I'd rather carry another 16oz of barrel weight than fight load development components and my time and disappointments.
