there ya go. "good" practice makes a better shooter. fundamentals as you said are key. heck Ive been shooting for the past 40yrs and find myself having to go back to the fundamentals and stop over thinking....go figure.
it at times amazes me that some days, you can get behind your rifle and your mind/body are as one with the rifle without even thinking about it. other days?....your wondering why the hell you even took the rifle out of its case.
