I own and shoot one also. But it's absolutely unrelated to their claim of improved heat transfer.
There's never been any technical explanation provided by Proof on their claims to improved heat transfer that I'm aware of. Otherwise, as a licensed engineer with training in heat transfer, I should have been able to find it while researching their claims. All I find is promotional statements, which I conclude are out of context with the realities of practical barrel heating and cooling, in order to promote sales.
Nosler inflated their bullet BC valued for decades. Do you believe Nosler, simply because they published false BC values? False promotional claims have always been used to increase profits, and they continue today, because it simply works. Sales are improved. I guarantee you false claims aren't employed to reduce profits.
By the way, if you always believed Nosler's bullet BC values, you might as well believe in the tooth fairy. Nosler only modified their bullet BC values closer to reality after they were irrefutably caught. Funny how human nature works when it comes to collecting others' money. Ethics generally have no role in the marketing department.
So ask Proof Research to provide you with their scientific research and explanation, including peer review with third party validation, that their barrels cool 466% faster than steel barrels. Post it here for us to read, so we can reach a determination based on something more than their promotional sales literature. Or ask any carbon fiber wrapped barrel manufacturer to provide the equivalent, if they make equivalent claims. I'm objective and willing to eat some crow. I'll review their "science" supporting their promotional literature. But don't be surprised to come back with a goose egg. Refusal will undoubtedly be accompanied with a claim it's proprietary and confidential. Which leaves us with nothing more than anecdotal evidence, the equivalent of, don't ask don't tell. Which is how Nosler misled their customers for decades.
