I am 70 and don't consider myself an expert in any area of firearms. I don't reload. I hunt for food animals and predators that threaten my property... but I don't go on safari to find them. I casual shoot quite a bit with 22's and shotguns with friends and family. I am on the net a lot sucking up the knowledge found in forums like this (and some others).
I started as a Boy Scout, with my interest in shooting nurtured by a scoutmaster and other adults in SoCal. Followed by 3 years in the Army, not a combat branch, but armed with a variety of weapons during my early tour in Vietnam (1962). learned about Auto/semi-auto and trench shotgun versitility. Hunted a bit as a young adult, but married and loaded down with 2 jobs and full-time college, then new teacher jobs stopped my outdoor time for several years.
As the kids matured and left home i got more interested in Hunting. A year in Idaho at one of the colleges there really got me into the deer/elk hunting. Then it was back to SoCal and desert living. The hunting became less attractive due to costs, but the casual desert shooting really grew as my adult sons came along and we really used up some ammo. Lots of time reading the reviews of new stuff and dreaming about what i wanted to acquire myself.
So here I am retired, somewhat limited in my movement, but doing a lot of sharing of data about the things I DO know a bit about. I am a low budget collector. I have several Rugers and S&W's and Colts, but I also have several Taurus, Mossberg, Saiga, and Charter's, which tends to put me in the lower class gun-guy group. No Big deal to me, I find, especially in this forum that the comments bad-mouthing a particular gun-brand, are not directed personally, but at the quality of the gun or manufacturer itself. I can respect that type of forum.
I read the technical data with interest, but I make a choice of buying or useage based on consensus of opinions from folks I respect....and on fiscal constraints that the budget allows.
My Advice to a person with a new-found interest in firearms is, take it slow. Learn the Basics, including the legalities of gun use in your area. Then Practice, Practice, Practice. There is no such thing as too much shooting practice. If hunting is an interest, then start close to home and learn from your neighbors...then expand to other areas as your goals progress.
BUT don't neglect family or other responsibilities , find a balance to your life and you will be a happy person, and have a life that will be the envy of a lot of folks.
Good Luck.
