I took a friend to my range last year and all he had were air guns to shoot. I'd never shot them before and after some trigger time, I became a fan, but because they were .177 caliber and it was a windy day, the effective range was about 10 yards. I'm not interested in a .177. I don't think they are worth it. As I've been trying to educate myself on air guns, it looks like .22 caliber is the best option for low cost, pellet availability, and a bit longer range and power. I'm down for that, but I've also seen that there are .25's, .30's, .35's, and even .45 caliber air rifles. Questions: 1. If I were to buy an air gun larger than .22, which is going to be the lowest in cost over the long term? Which pellets larger than .22 are most common and easy to find? 2. Is it worth it to buy an air gun larger than .22? Is the cost that much more?
