It's a question of price, at $325 a barrel they are competing against the best of Shilen, Lilja and Walter. And, as you said, it's been quiet around them lately, so it's hard to justify the expense without proof they're still among the best in the business.
Barrels in this class are so hard to compare because you can't just go and pop 4 different barrels in a gun to test, you need to do load development for each, and the one that shoots 10 mm groups wins over the one that only does 12 mm at it's best.
