Hi all, I was wondering if there is a rule of thumb for moving a barrel tuners direction in relation to bullet speed ? I shoot 22LR benchrest with a lowey tuner and when I buy a new batch of ammunition it may vary 20 fps or other brands may vary more.
I don’t buy large quantities at a time and often my last batch number is not available. The ability to get back on tune quickly would save bullets.
I have experimented a little and it seems the faster the bullet the further out I need to turn my tuner.
Any help would be greatly appreciated
