I have a definite preference for .222 Remington - but do not see where one would be better in a bolt rifle than the other.
By all reports, they both work just fine. I have owned CZ rifles in both calibers - and noticed no difference in how the cartridges functioned in those rifles.
.222 Rem has a big edge in my estimation because it is well-established as a sporting and target-shooting round, and is not even vaguely "tactical".
For me, "Tactical" and "Over-priced junk" are synonymous.
Once I was asked about my opinion of the Texas state lottery... I replied that I fully approved of the "fool tax" as it allowed others to volunteer to pay taxes - so that I would not have to.
I don't approve of the "tactical" fad though as it raises prices for all, not just the tactical aficionados, and I feel that this is essentially unfair.
