How does altitude affect it? Does the air density affect the harmonics of the barrel?Even altitude changes will impact the barrel tuner. It will have to be tweaked maybe.

Thats great to hear.After 500 rounds and 8 different bullet and powder combinations trying to fine tune loads for a one hole group, I installed the Cortina unit and after moving the tuner dial from zero to 2.5 I shot this group. I ran out of time so I am going back to the range to see if it will shrink some more and if its repeatable. Up until I installed the tuner I could only get 3/4 moa out of this rifle with this load or any load for that matter. The rifle is a Ruger american in 308 installed in a boyds stock with a matthews cheek rest and a 4x14 power leupold. Brass is 3x fired Lapua, 42.0g benchmark, CCI BR primer and a 155 barnes match burner set at .095" CBTO.
I am now a believer.
