my son will be taking his first attempt at harvesting a deer this year. i'm really considering getting a .243 barrel for my handi, because i just don't feel comfortable with the .223 barrel i have for deer. any opinions on the .223 issue? it will be close shooting, most likely less than 50 yards. anyway, i was wondering what is the average turn around time on having a barrel fitted and returned to your home. a couple of weeks?
