Hi,
Shooting a quality air rifle also helps a lot in rifle shooting.
I have often thought about getting an airgun, but the area I live in wouldn't permit me shooting an decent airgun in my backyard, and If I do have to go to the national forest to shoot, I would rather prefer to shoot my rifles. Also good quality PCP and break barrels almost cost as much as regular firearms, so i find it difficult to justify buying air rifles.
