I need to see more/talk to more people about the "actual" increased life. I read something about a 11" barrel shooting 1" at 100yds after 15K rounds. That doesnt mean anything. As the throat wears, its the long range accuracy that suffers. I have seen many several thousand round barrels that are toast and will not shoot at 600yds, but still shoot MOA at 100yds and even 300yds!
I sold a Denny an SS 11" Pac-Nor barrel a couple years ago, he said it shoots MOA all day long. If someone wants to take the time to shoot groups at 100, 200, and 300 yds and compare groups over time that will tell much more.
These may be the greatest thing since sliced bread, but its too soon to tell for me. Until I get more input from the people I trust, and rely on, I'm sticking to what I know works.
I'd rather know for myself and my customers whats really what, instead of blowing stars up your skirt about the latest tactical more better marketing buzzwords, regarding something I have little to no experience with. As I said, too new for me.
