RE: Could a 222 be used for..................
Frizzelr,
I used to think that the .222 was more accurate. Until I seen one of the US Army's .223's in action. Very impressive to say the least. The person shooting it was using a peep sight and keeping the groups in the .1 moa range.
The rifle was built on a Rem.700 action, and had one of the neatest externally adjustable triggers I have ever ran across. If I remember correctly each one of these rifles cost the military around $4000 each.
Rem. 222
