As an aside I have a Remington 700 BDL Varmint in caliber 222 Remington with a period correct Redfield 6x18 variable scope on it - and in my somewhat limited "load testing and sight-in verifications over the years it's best group (5 shots at 100 yards) measured .218"!
Very nice combo! ......... A lot of those old 700 222s got torn down for the action or rechambered to 223.
Rechambering is/was apparently a good way to stretch out the usable life of a barrel, according to a piece I read a while back. The writer cited a pal who put about 12,000 rounds through his .222, rechambered to clean up the throat, and soldiered on as before. Should appeal to the frugal sort, maybe even me.
