I took the Avenger out back today and put the Pro tune on it and that's where I like it for now. JSB 18.13 @ 901 psi, es 14, div4, 15.89@941psi, es10, div2, cros 14.3@970, es9, div2. These are ten shots string from 300 bar fills. Then I put five shots at the chrony just to see what the 25.39 JSB would do, 775 average for five shots, es10,div4 and last as it was getting late in the day five shoots from 21.14 gr H&N baracuda av839, es6 and div2. I'm very pleased at these numbers. My reg pointer on the gage is left of the 2000 psi mark so I assumed it is at around 1800 psi and hammer spring from backed out to 2.75 inward. The shots were going straight and no chipmunk will get by if I do my part. That's it for now !
