I've shot a couple more fairly long strings with this tune. The first tune started at 200 bar. It was 12 shots sighting in my 32X scope for shooting targets and then 24 shots on a 30 yard challenge target. I ended at 100 bar. If I ignore the last 4 shots I think the ES was 22 fps. The final two shots were Xs, however, with a velocity of 756 and 751. I scored the target at 189 with 10Xs. The best I've done with this gun is a 194.
Today I shot 40 shots starting at 220 bar and ending at 110 bar. The first 24 were on a 30 yard challenge target and the final 16 were sighting in the 4-14 scope I put back on the gun and messing around a little. The ES was 26 without the final two shots (765 and 759fps). The Average velocity of the same 38 shots was 785 fps. The first 25 shots (the ones I think were on the reg) averaged 788 fps. 13 of the final 15 averaged 779 fps. Fpe ran from 45 to 48 fpe. Todays target was a 190 with 10Xs.
The ES is a little higher than I would like but it doesn't change by incorporating the final few shots. It might have been made worse by my chronograph shifting a little while I'm shooting. There is enough of a muzzle blast it twists the chronograph sometimes. I changed the way it is mounted before shooting the last 16 shots and the ES dropped to 10. So maybe part of the 20s ES is measurement. I am not seeing point of impact changes.
