So today I took my son to the range. We did some work on the bench rest at 100 yards. Gun is noting fancy an old Remington 597 with a VQ target hammer and a Nikon 3x9 rimfire and CCI Standard velocity ammo. He has shot combined military the last couple months at the range and his groups always have at least 1 flyer using a club trainer. So the plan was to have him practice today with no pressure. Take his time play with the scope whatever he wanted to do. Today the wind was supposed to be less than 5 today it was probably 7-8 most of the morning. He was shooting off a Rock BR front rest and rear bag. My main goal was to get him used to making scope changes and checking the spotting scope. I had him shoot 5 shot groups multiple times. He consistently would put the first shot high left. I am talking a few inches high and left. This was after he made scope adjustments and was settled in. After talking to him about it and my belief it was him jerking the trigger. On his last group he purposely held low right without saying anything to me and it hit right where he aimed. Any ideas what I am missing. His second and third shots were double taps multiple times. I made sure he was keeping his cheek weld the whole time, had the stock tight to his shoulder and trying to pull at the pause in his breath. I even had him try some eley ammo same thing. I wasn't to concerned with group sizes just that each time his first shot goes bonkers. He was shooting 4 mags in a row of 5 shots each. Then we would patch target and go again. Anyone have an ideas what is going on?
