I found a local club on the internet on the web sight of the shooting sport that looked intresting. IDPA. Called the guy who ran it and showed up. My first few months of shooting, I sprayed bullets all over the place. Now I just hit my targets once and awhile. Showing some progress, but I still have a long way to go to get serious.
To gauge yourself, try to improve some every time you go out. They will always be something to work on, reloads, drawing your firearm, getting the proper sight picture all the time, hell shooting the right targets. Always something.
Just get out there and have fun and be safe.
