Scopes are great tools. Shooting well without one will usually help you make the most of shooting with one.
This is a personal opinion. But shooting with a scope will help someone shoot without one. In over 50 years of shooting, I have found that seeing your target without the front post covering it up is essential to hitting the target in the correct place. (or do you use a 6 o'clock hold?)
The OP has never fired a rifle before and unless someone is willing to sit down with him and teach him how to drift his front sight and walk in the elevation on his rear sight a scope will have him learning trigger control and proper breathing much faster and make shooting much more fun for him. A scope requires the rifle to be locked down, take one shot and then adjust your cross hairs to the bullet hole and you are ready to go.
This is not a hunting post, but if it was I would tell you:
A) After any amount of travel, check your scopes zero in camp, BEFORE going in the field.
B) Always take 2 rifles with incase one fails (jams) or is dropped down a hill or into a stream.
C) Don't, let me repeat this, DON'T drop your rifle or put it on a slop where it will roll down hill.
D) When all else fails, take a second scope (or optic) with just incase or get a compond bow. (it might be safer for you, LOL)
