I have over 1,000 rounds .223, 600-700 rounds .204, 200-300 rounds .243 and 2,000 or so of .22 rimfire and about the same .17HMR. Also have about 500 rounds each of 12 and 20 ga. When I realized how much I have, I thought that seemed like a lot, but I have lots of friends who have a lot more than that. I reload all my rifle, but do not reload shotgun shells. At gun shows, I have found some really good deals so I buy a bunch when I find such bargains. My general rule of thumb is to keep around a 1,000 rounds of any rifle ammo that I shoot lots of prairie dogs with----.223, .204, and .17 HMR. I have gone with 500 rounds of .223 and ran out!!
