Hello everyone while back I bought a reload set up with all the fixings everythings like new. It came with this chronny I think and for 3 buttons you’d think it would be a bit more on the user friendly side…. I have got it to work after setting up fps + the bullet gr converted into grams as the “simple” instructions state. 1 outta 5 times I get it reading fps for 10 shots then reads improper, 4 outta 5 times it lands in joules and then it reads very improper even after joule conversion. Anyone have this piece and can explain so I know what I’m doing with a bit more success would be much appreciated!!
