Re: A few questions.
You can start out with whatever you want; but the advice you have received on starting in .22 caliber small bore competition or air rifle competition is the best idea. LEARNING THE FUNDAMENTALS OF SHOOTING is what you need to do right now. then once you upgrade to any other rifle, the fundamentals will always be there!
Also, you need to change your "signature" on the bottom of your posts, SOLES should be SOULS. 10-4? Stay interested, READ, READ, READ, AND THEN READ SOME MORE. KNOWLEDGE IS KING. it will also help you be able to separate the bull shitters, from those who have been there and done it, ya know?!
