Hi fellows

I would like to share with you some groups that I achieved with the gamo Accu ,4.5 caliber at 22 yards, 5 shots per target

clearly an accurate gun at the distance you gave. I notice the topmost row of targets seem to have the tightest groups - nearly pellet on pellet - while the bottom-most targets have groups that are a bit larger but are centered on the bull. Can you tell us what the chronology of these results was? Did you adjust the POA over subsequent targets to zero on the bull? Can you tell us what you believe is happening to cause the noticeable difference in the group sizes?

Hi IronLion

I would like to ask your comprehension if i make any mistakes in my writng...my english it is not very good!!!

The botton targets are the first ones and the above targets are my last ones, this rifle is modified with 40kg gas ram spring and also with a 115 grams piston, the velocity is around 691 fps with 8,33 grains pellets. I think that the change in poi is related with the accommodation of the internals ...as I remember I didn't adjust the scope in order to adequate to the bulls eye; it was all consequence of the accommodation of the internals.
The group size is related, i belive, with my position of shotting and the way I make it consistent in order to obtain tighten groups and my shotting position was bench rest,
