Shootable range is nebulous. Punch paper....perhaps a thousand yards. Kill a woodchuck, perhaps 300 - 350 or so. A deer, a man, a wolf, not so far. A lot depends on the shooter, the load, the optics and the target. I keep my 223 inside 300 yards, the .22-250 out to 500. .243 300 - 400, etc. I keep my rifles sighted for specific yardage and grab the rifle the shot demands. Living on a farm presents targets that change daily, hourly, sometimes minute to minute.
Shooting off the bench, shot after shot, the bull barrel is an advantage, but hunting with a cold barrel, I think my Superlight .223 will match the bull in accuracy.......it will sling better and give me a lot less to lug around the bush.
