Hello all, I have some basic, straightforward questions about learning to shoot on the AR platform.
1) Using a barrel that has sub-MOA capability at 100 yards, I was able to zero in my rifle with the help of a gentleman who had a good spotting scope. And at 50 yards had an ~7"(including the last few rounds of my zeroing- so that's not all just bad aim). But I hold my head so close to my rear sight that my nose is touching my charging handle(just as an Army Shooting Instructor told me to years ago as part of a JROTC class) to maintain consistent shot placement. The problem is that to me this feels unnatural. When I bring up my rifle I feel comfortable when my head is at ~1/2-3/4 forward on the stock. The other problem is that I have seen other people/military shooting accurately with their heads being 1/2-3/4 on the stock. So while the Instructor's way is correct, I feel like there is more than one way to peel this banana, right? As someone learning to shoot, would there be anything negative to keeping my head where it feels comfortable(and what risk of inconstant shot placement would there be)?
2) I am left-eye dominant. I am right handed. Holding my rifle in my left hand feels terrible. Not just "this feels good but this side doesn't feel as good", no I mean it feels almost as if when I switch hands my right arm suddenly loses strength, or my left hand suddenly goes wobbly on me. I know it's an idiotic gripe, but I just don't like at all the feeling of shooting left handed. I have been told that when I get into the Marines that dominant eye will be the thing Instructors go off of, not comfort, so my question is; to anyone who is/separated from the Corps will the instructors teach me to fire from the left? What if I turn out to be proficient from the right? Would it be better for me to learn to shoot with my dominant hand, or force myself to learn with my dominant eye?
3) Am I freaking out about nothing? Getting 7" grouping at 50 yards, so over a foot grouping at 100 yards, even if all other factors being equal and my aim is this bad, is there any realistic hope that going to the range with no instruction, I can be accurate enough to hit a 1" target at 300 yards within a year? Or should I pay for basic shooting course(s) and try to learn from someone who knows more about what they are doing than I? I hate to admit it but part of my apprehension comes from hoping I am not in a class with my AR with a bunch of 8 year olds wielding My First Rifles. Again, stupid to think about what other people think but, it is something which would detract from my self esteem.
So there it is. I would appreciate any real help.
