[QUOTE="J E Custom, post: 244032, member: 2736"] Probably not . Most of the early 220 swifts and 22/250s were 1 in 14 twist for 45 to 55gr @ 3700ft/sec + They did not make the heavy bullets back then. If your wanting to shoot 70gr bullets @3100 you will need a 1 in 7 or 1 in 8 twist and you might get buy with a 1 in 9. Also the throat is longer normaly because in there day these were very hot loads. Don't worry to much about freebore ! Just fire form your brass and neck size only and it will supprize you how well it will shoot unless the barrel is used up. J E CUSTOM [/QUOTE]
