Safety
Learning how to handle a firearm correctly has been one of the biggest skills I have acquired. I have learned to always think like my firearm is loaded, when you behave this way you can always rest assured that your being safe. Keeping constant attention on the direction your firearm is facing is critical as well. It takes not only physical training to shoot safely but mental training as well.
Accurate shooting
Accurate shooting is not as simple as just holding you gun steady it also takes a knowledge of the type of ammunition your shooting and an understanding of you related distance. This is one aspect that I have practiced heavily but becoming a professional takes years and years.
Valuing
During the course of this project I have also attained the skill a valuing. Inadvertently, I was able to gain a huge understanding of buying and selling firearms as well as pricing modern and dated guns. I spent quite a bit of time in a local gun dealer studying the pricing structure of several firearms, with the aid of an employee from the dealer and a value book. This skill is very valuable for someone interested in collecting and purchasing.
