I have this:
And I can't shoot a consistently small group to save my life. Recently upgraded the scope from a Vortex PST 2.5-10x44 to a Nightforce 3.5-10x, and groups remain the same. It's not an ammo issue as I've tried multiple ammo types and for the most part they've all been the same. To my chagrin, they've averaged 1.75-2in groups, anything from standard ball mil surp, to heavy OTM from Black Hills, IMI, CBC, ADI and others, including my own 69gr SMK handloads with Varget.
I am very sure it is me sucking badly. I am good at combat shooting, fast and minute of man accuracy. But when it comes to shooting tiny groups, I can't do it. I've done plenty of dry fire before, perhaps I need to be more consistent at doing that every night.
The Nightforce has a parallax knob on the side which is new to me. I read the scope manual and for the most part I understand it. To my eyes it made the reticle and target more crisp instead of one or the other blurry. I tried the head nodding and moving side to side but either my head moving the rifle made the rifle move or the reticle kept moving.
I've read that ARs are more unforgiving than bolt guns. I wouldn't know as I only shot bolt guns when I was much younger and then joined the military and everything I've shot since then has been an AR type weapon.
Not really sure what to do at this point. I am pretty certain the rifle and ammo combinations are capable, it's just the shooter. Where would you start a new precison AR shooter? What's the beginning step, more dry fire?
