If you see yourself as being unable to take a life, don't get into sniping, as that is the whole point. But if you are interested in the long-range precision aspect of the craft, get a good rifle and spend a day every once in a while at the range. Heck, you can even shoot paper silhouettes, and perfect the sniper skills. I am sure you will find it is a lot of fun. And check with local rules and regs to see about age minimums. Good luck, whichever route you take. And by the way, I am not a sniper myself, but do do a lot of long-range shooting and like discussing and sharing knowledge on the subjects with others. If thats what you like to do, then you've come to the right place, my friend!
