Wildcat MK3BT Compact .22 with 600mm and 500mm barrels. STX Superior liners. Shooting off a bi-pod and rear bag.
I spent hours and hundreds of pellets and slugs attempting to tune out random flyers as well as POI shifts.
2nd reg pressures from 115 - 145 psi. Hammer spring adjusting for each new reg setting and each shot chronographed.
I cleaned each liner before using and again around the 150 round mark to make sure I wasn't experiencing fouling issues.
I was having flyers show up all of a sudden and sometimes this was also a POI shift as well. I was completely stumped as to what could be causing all of this when my wife sat down to help take notes and observed the barrel movement would sometimes be different than it was the shot before. My bench was stable, it must be me! As I set out to perfect my shot to shot form I quickly realized I was fatigued from hours of shooting and that my gun was sliding forward. The legs of my pi-pod were sliding on my bench when I would load it slightly - in an attempt to have the same form every shot. I also found that with the legs angled back towards me and extended I was getting flex or even bounce at the muzzle - as witnessed by my wife. Knowing this was an issue with powder Burners, IE having the legs in almost any other position than straight up and down, I put the legs straight up and had much better results except for the lack of grip on then bench. I did still have a fair amount of flex/movement in those legs. So, not satisfied, I put the Accu-Tac on and my flyers were gone! I did still have some vertical POI shifting which was directly related to my lack of form. I could even fold the legs of the Accu-Tac forward or backwards without any flyers. To further test things I shot from a front and rear bag set up which eliminated the vertical stringing.
The lesson here is to account for all your variables and prove them out and that in somethings quality is usually a much needed help.
