I am using a Marauder 22 cal stock rifle Walther barrel Pic scope rail on top
When I am testing I will shoot 5 shot groups the group size at 25 yards is good ( around 3/8" outside to outside) with the 18 gr JSB pellets
I will shoot 5 groups and then refill
What happens is as I am shooting the groups the groups wander around the aim point
Example one group might be at 2 o'clock then one at 6 o'clock and another at 10 o'clock they are not far away from the aim point but I can't figure out why they wander
Right now the pellets are 825 FPS with a spread of about 10 FPS
I am shooting off of a 1 piece rest with a 3" wide block mounted on an Anschutz rail on the forend. Rifle is scoped with a Bushnell Match Pro scope
