I have a new Marauder Synthetic .25 cal that now has about 300 shots through it. I am noticing that the Point of Impact consistantly shifts from left to right about 1.5" at 40 yards across even just a 16 shot string.
So at the beginning of the shot string it is 3/4" left of bullseye and at the end of the shot string it is about 3/4" right of bullseye even though the velocity is the same. Up and down is unchanged and the gun is otherwise very accurate. This is the factory tune which I thought was perfect according to the chrono and small group accuracy.
Is there a way that I can minimize this issue by fine tuning? Other suggestions?
Here is a sample of my shot strings, velocity measured at 10'. 25.39gr JSB Kings.
Pressure 3050
844 POI is 3/4" Left of Bullseye @ 40 Yds
