Good point--I typically will break in my .22lr. semis with either the CCI or Aquila hot-stuff. Once I have done so I use the cheap bulk stuff almost exclusively to save both money and wear and tear (my BUG's always have Stingers). The example that immediately comes to mind is the SIG Mosquito which consistently jammed on all ammo until several hundred rounds of Stingers were run through it. It's kind of analogous to how I use the +P ammo in my larger calibers.
