Update- I think problem solved... increased height of cheek piece with foam under stock pack. Now a comfortable and repeatable cheek weld can be obtained without straining neck. Apparently, I've gone all my life and never had it right A month ago was my first long range match/shoot. Course of fire was about 50 rounds total at 200/400/600 yards, broken up over a few hours and working the target pit. It was my first time ever shooting prone and the following day my neck was awfully sore from craning my neck up. Several questions... Is this normal? Expected? Or is it a symptom of poor technique? I've read multiple articles on prone shooting, but no formal instruction. Thanks.
