Brian don't you find the bigger bullets makes for easier tracking of wounded animals?
We have tons of hunters with 6.5x55 here, and it is a good round if placed well, but pigs and moose can tend to not bleed too much from bad hits, same placement with a 9.3x57(another pretty common calibre here) leaves much more to track
now this is circumstantial at best becuase it is not like I am a professional tracker or anything
And more concerning the topic the .222 is great for our most common deer the roe but I have a sneaky suspiscion that a big deer for us would be a tiny one for you
