should add that my velocitys are from a magneetospeed sporter. battery at 7.4v. not sure how much of a difference that makes compared to a garmin. I'd like to try it over a few different chronys some day.

thinking I got a fast barrel. haven't played with varget at all so I can't say what you'll end up at. but if you cant get what your after id try out N540 or even N550. seems decently temp stable. haven't shot it in the 80*+ days or -30 yet. but it's been acceptable from 20 to 60 so far
little late to the party but never made an account until now.
I'm shooting a 20 inch 7 saw type 1. so the short chamber. 139 barnes lrx N540 powder I'm at 3020fps. had a pretty good ejector swipe at 3079.
did email wto and Clayton said I might have gotten a pretty quick barrel.
160...
