Greetings to all. My name is Clint, I am 74years old, and a Vietnam era army vet. I am a lifetime PA deer hunter, but I am new to longe range shooting. Will be going on a WY antelope hunt in about a month. Due to a lifetime of less than ideal posture, my neck is slanted forward, and is difficult for me to get a good mount on my bolt action 25:06 rifle with a low height bipod. My outfitter tells me that the vast majority of shots are taken from prone position. Trying everything possible to be able to get the best sight picture without painfully straining my neck backward. Also working on finding the best breathing pattern to eliminate rise and fall associated with a sitting position. Any helpful suggestion are welcome
