If you are keeping your shots within the 300 yard range, the .223 is very viable with lighter bullets.. I have a 1/9 twist .223 that will hold them inside a nickel at 100 yards without any real challenge on my part..I have a Rem 700 .223 with a 1/12 twist barrel that will do even better with bullets up to, and including, 60gr...
Agreed, however if the 204R had been introduced with a -10 twist it would have been a whole different ball game. With the -12 twist in 204R [or any 20 cal.] you are limited to just a few bullet weights [39gr being the heviest], making the .223Rem much more versatile. If on the other hand you build a 20 cal. and put a 10 twist on it, you would be in a whole different world. IMO.
BTW, if I were to go down range beyond 300yds, I will want a bullet with more than 39-40gr weight. Something a 223 can do, but a over the counter .20 cal. cannot.
