Usually something to do with vision, wind or pellets. Once waxed a stock for the winter months and it was slicker than running bald tires in a tropical storm. Was using a See All sight and was struggling to get decent groups... Must have been struggling to get a good sight picture (then grabbed second rifle equipped also with see all sight, first shot 9'oclock just off bull and the next 5 or 6 in a ragged hole ). As of late, "I don't understand, my form is perfect so somethings wrong with that gun"
Every year now I realize a decline in my vision.. that rock steady , hawkeyed 20 year old ain't no more , that's for sure
"20 year old ain't no more" i find this applies to most projects now day's ! only with me it is 40 year old . HAHAHA
