Failed the Jeep-stress-test.
After riding around in my Jeep to and from work (a 17.8 mile trip) on the floor boards (in a soft case) the point of impact shifted quite a bit.
So went back to the old barrel band setting of near the muzzle (the rear band still just ahead of the breech).
Almost as accurate (statically the same for the small tests) but has proved to be more stable at this point. Have done the Jeep Test for a couple of weeks at this setting and found the POA/POI to have stayed stable, so that's where this Disco is going to live.
Teat targets at the new (old) setting: 5 shots/2oyards/ 13.5gr. AA pellets:
Rifle will get another trip to and from work, then tested...and if it passes that test, will get trips and tests every day for the rest of the week.
What I want is decent accuracy and a stable point of impact...may be ways to eek out more accuracy, but if the pellets aren't consistently to the point of aim, it's not a useful gain for hunting.
