Over here we have Winchester Z-Longs (or Zimmer now I think) which appear to have similar specs to the CCI but with the shorter long case. I haven't tested the accuracy under fair distance and conditions (I've only tried them at 50 yards but accuracy wasn't real good as a result of the variable wind on the range - on that day couldn't even get the accuracy out of the rifle with the standard velocity standard ammo that it likes).
