That’s right but I did just put an order in for an 8 Twist Krieger... got a danged pile of 180 BBCs that need a good launch!
I think you'll be pleased with the Krieger barrel. They built my 6.5-06AI from parts I supplied (stock, action, trigger) and a 1-8 fluted barrel they supplied. Last time I had it at the range splattered 5 clay pigeons on the 600 yard berm with a total of about 12 shots. I'm very pleased with the quality of that barrel. (And the other work they did.)
