Yep! That's the way high magnification scopes work. Eye relief and centered eye position more critical at higher magnification than at lower magnifications.
Yeah it gets finicky at high mag. That's why most run at about 75%. I have a benchrest scope that goes to 50 power and at 40 it's fine but at 50 it's almost impossible to stay behind it consistently.
Well I believe I've got all setup. I went shooting today and alworks great just got a whole lot more practice. Thank you all for your help I'm sure I will have more questions in near future.
