I will have to call and ask. If they do, in a hunting version, you can all expect to see a review very soon.

Yup, it would be a beast. I'm thinking it would grow by about .100... probably need a faster twist which would rule it out of my rifle.

we'll see, I'm running an 8.4" twist. At WSM velocity it may just stabilize....

I'll post what I find out.

They told me to order a 7 twist barrel for the 140 and a 7.5 for the 130.

Well, mine will be an 8 twist, so if it stabilizes in yours I'm good to go. I'll be watching with interest

Their site says an 8 or faster and my e-mail says a 7.5 would be perfect because they would be stable down to sea level.
