From the CZ-USA website...
Q: ?I?ve heard you use tight bores in your .22s, is that right? What does that mean??
A: Our 22 LRs use our cold hammer forged and lapped barrels, and are built a bit tighter than many other guns. In 22 LR we run a .211 bore, which is one of the reasons our .22s are known for incredible accuracy. This also means that a .17 or .20 rod and jag are required for cleaning, since a .22 rod will be too large.
Additionally, use of .22 Short, Long and ?Sub-Sonic? ammunition isn?t recommended because of the tight bore. This is not to exclude quality match or target ammos, which may remain sub-sonic in speed
This is why you need a smaller cleaning rod or bore snake.
