Airgunning is an EXCELLENT training ground for shooting.
If one can shoot an airgun well - he/she will be able to shoot anything well. I highly recommend giving it a try. Plus you can set up a mini-range just about anywhere you live for an airgun - there is NO substitute for behind-the-trigger practice.
Working with my son with his air rifle team has made me a MUCH better marksman..................... and he's going to the 4H National Finals next month too!
