I have finally started to test my 22 mag CZ452 and the best performing ammunition appears to be the Remington V-Max with a 33 grain HP. This is a mini plastic tip bullet from Hornady loaded by Remington. It feeds very well in my rifle which is something the CCI and Federal offerings won't do. It also appears to be very accurate and consistent from the limited testing I was able to do yesterday due to the high winds when I was shooting. Anybody have any experience using this ammunition on gophers and maybe fox or coyotes? Thanks for any info. Steve
