I went into intervals of 2 (of 10) and shot 5 3 shot groups, picked the best and went back to it and confirmed. I understand 100% that my sample size is a little on the small side and I could probably find more gains, but this barrel is getting close to 1k rounds.Good shooting! Groups look good. How much tuning did you do with the Ed brake tuner?
The EC tuner brake didn’t work for me on a 6cm mtu (or comp contour, but similar) running 6cm hornady factory ammo. The weight is likely too small. But I am a sample size of one. Hopefully others have very good experiences.
Also, the ATS has been changed to a tapered model that is much harder to catch on things. I merely pointed out that the straight edges would be easy to catch. I’m sure he made some videos showing it not catching. But now it’s a better shape than it was and everyone is happy.
My experience was different, with a 24" proof competition contour. Also sample size of 1.
