What was your powder and primer of choice, and did you seat into or off the lands?I shot 80gr SMK in a 1-8 twist for NRA high power competition and it shot very well at 600yds.

Thank you for posting your results and load. And thank you especially for posting your barrel twist rate.
What altitude do you typically shoot? I'm at 980 above SL, and found my 80 SMKs were marginally stable in my CBI 8 twist. Maybe I just wasn't driving them hard enough.
I'm 5100 feet in Colorado, so there may be / are some differences. Also, since this earlier writing, I have gone to 24.5gr of Varget. Last F T/R match shot a 550 5X - not my best, but not the worst either. (Dang shifty wind - yeah that's it)
But with increased load I notice a little problem in seating and from 6.5 Guys video I learned about how settle the powder. I am now using a battery powered razor placed against the case to settle the powder.
