Went shooting today, had a job on a farm and took the CZ .22 Mod11 along. I have found that I have a growing love for the .22 caliber, even in center fire.
I am enjoying it tremendously learning the trajectory and behavior of different ammo.
My rifle is zeroed at 70 m and I am shooting Remington Thunderbolts ( I have to ...... they cost less). Now the thing I wish to ask is regarding the grouping - the two groups that form. I shoot a shot note hole and shoot again and again close group with one hole a inch up of group forming below, carry on shooting - and 40/50 shots later there is a distinct two groups, both good groups, but in different places.
I have my own theory, but would like to know what others say.
Shot the Guerrilla ammo later - one group.
What causes two groups ?.
