I keep 200 rounds of defensive ammo for my EDC and 100 rounds for my S&W Airweight that I carry sometimes. I've switched brands of JHP a couple times (went from Golden Sabers to Federal HST and finally landed on Speer Gold Dots) so I haven't had a chance to work on building up a pile. I usually shoot a mag or two once every couple months and buy a couple new boxes months to try and keep a decent supply.
