I've never counted but I'd estimate I probably go through around 100 - 200 rounds a year. If I shoot for another 50 years, I should be around 5,000 - 10,000. Not a lot based on what others have posted but my father taught me that accuracy is far more imortant than how fast you can burn through a box of ammo.
Guess I'll never be accused of being the cause of the current ammo shortage. lol
