I myself was enamored with the ballistics of the 22 CM until a wise old man told me to look at the .224TTH
My lust for the 22CM quickly faded when I compared barrel life, bullet speeds and accuracy with these two
The .224TTH has been around since the 50’s mostly as a wildcat but has brass and dies available for reloading like the 280 AI
I own several of the newer cartridges and can say there is no noticeable difference in what I can make them all do when comparing bullet diameter and weight


When I need expert advice I tend to talk to myself
The older I get the better I used to be
