[QUOTE="J E Custom, post: 1460584, member: 2736"] The free bore is .360 (.003 thousandths larger than the bullet .357) [URL]https://saami.org/wp-content/uploads/2018/01/Z299-4_ANSI-SAAMI_CFR.pdf#page=13[/URL] Lots of the older cartridges have this amount of freebore diameter because Older bullets were not as precise as they are now so Maybe they wanted to be sure that there was enough clearance. Newer cartridges are generally around .001 thousandth. (.0005 per side) That may sound like a lot but it is not. Some cartridges have .004 freebore diameters. J E CUSTOM [/QUOTE]
