RE: sighting in a scope
Q,
I agree with you about the hunter safety course is mainly to instruct about safety, and not much about firearm details except safe handling. An instructor has a lot of teaching in the basics and usually has a full class. Unless he has a lot of time, it is hard to touch on everything. I have thought many times there should be a course on marksmanship, gun technicallity, etc.
Start looking for some books on marksmanship, shooting and the mechanics of the firearm. There are dozens available, some good, others excellent. spend some time reading. One thing for sure, it won't hurt.
Keep an open mind when reading, there are as many opinions out there as there are writers. (I bet now I have you completely confused). I'm 71, been shooting since 1947 (Boy Scout camp, Asst. Rifle Range Director). I'm still learning.
