Let us know how it shoots. I built my son a 223 on a long action using a stainless fluted varmint weight factory barrel with 1 in 9 twist. I installed a single shot sled and his rifle is a tack driver with 69 grain SMK's and 75 gr A-Max or BTHP's. It regularly topples the steel pigs at 300 yards on our club range using either bullet weights.
