Thread: Subsonic 22LR round for hunting?

I have recently bought a CZ455, and been going through the different makes of ammo to see what works well. It has the 20" barrel, and is suppressed, so I have only tried subs.
Both the CCI and Winchester 40 gn subs grouped well. The winner for grouping was the remington 40gn, which was a real surprise as it was rubbish in my previous rifle.
To my shock, about 1 in 10 of the remington rounds would go supersonic, so were ruled out for a hunting round for use in the orchards.
The CCI when recovered from game (very rare) had very little deformation, and just did not open up. The Winchester and remington rounds were a lot better in this regard - as detailed by others previously.


I'll throw some Eley Match ammo through it soon, just so I can see the rifles true potential.
