I received my JSP tuner and need instruction on where to start. I’m wanting to know at what point the tuner is at zero. There doesn’t seem to be any place to start from. Any advice on this would be greatly appreciated.
I know Jonas has a procedure. So does Chris and they may be different.
Chris’ method:
1 - screw it close to the crown, back it out to the zero point.
2 - start shooting groups every 1/8th of a turn.
Jonas has another way. But hopefully Chris’ helps?
Okay, and I’m assuming the crown is the interior lip. Is that correct?
Just make sure you don’t rotate so far that either o-rings are exposed. 3 full rotations is what its capable of.
