Is that warning just to keep somebody from loading up their .22 mag revolver with .22WRF? I know that the bullet is about .001" bigger in diameter than regular .22s. I mean, there's nothing special about CCI's .22WRF that would prevent it from working properly in a revolver specifically chambered for .22WRF is there?
You answered the question, 22 Lr range from .222 to .223 and magnums run .224 so if your revolver bore is not .224 you will be running higher pressure.
Good intentions will always be pleaded for any assumption of power. The Constitution was made to guard the people against the dangers of good intentions. There are men in all ages who mean to govern will, but they mean to govern. They promise to be good masters, but they mean to be masters.
