poi change with high pw seting?
set up my talon ss with 22” brl to shoot some 40 yrd groups first 3 shots went in the same hole but the 4 hit high an to the right 5 low and to the left and kept chainging every shot after that ❓ i wasent holing the rifle it was on a gun vise and it didnt move at all when i moved the pw from 10 down to 7 it went away all shots very close to each other less than half an inch , i was shooting jsb hevies and the tank was at 3000 psi. does high fps cause that poi change or the tension of the hammer spring gets to inconsistent any ideas dont have a chrony so dont now how fast its shooting any ideas why this happens
