Distance for checking pellets
what is the normal distance you will use when trying to find the right pellet that suits your barrel ?
at the moment I have been testing at 55yrds but am I correct using this distance because at 40yrds I am certainly getting totally different results, with 55yrds being the furthest I,m shooting I thought I would start there, I,m basically looking for the pellets to stay on a horizontal line and as tight as possible,
is this the correct method
