When my Kimber was brand new, I ran 200 Hydra-Shoks through it. No problem. Recently, after about 10000 dounds, I fired all of my old Hydra-Shoks and 200 HSTs through it. No problem.
Keep in mind, 200 rounds is enough to force you to use different magazines. I'm not anal enough to track lot numbers, but I will buy the test ammo from different locations. During the test, I will also shoot with the weak hand, one-handed with both hands, emergency and tactical reloads.
