Grendel at extended ranges?

That's very good. I'm really suprised at that. I haven't found any 1/9's that will stabilize anything over 69's. 1/8's will usually stabilize up to 77's, and a few will stabilize 80's, I've heard. Even longer .223 barrels, like the 26-30" used in F Class have to be 1/8 to stabilize 77's from what those guys tell me.

Any chance that barrel is actually a 1/8? ( I ask because I have an upper that was sold to me as 1/9, but is actually marked 1/8 once I got the handguard off.

There actually is no markings on the barrel. It was purchased as a 1/9 24" bull barrel from i think centuron or something like that. I cut it down to 21" and have great luck with it. using a cleani.g rod its around a 1/9. I know thats not an exact way to measure. I haven even made hits on a 1000 yard target with it.
