[QUOTE="MontanaRifleman, post: 339238, member: 11717"] Aldon, Here is a link to a great site that shows case drawings and dimensions... [url=http://stevespages.com/page8d.htm]page8d[/url] You will see that the OD of the base of the 280 Rem is .470 and the OD at the shoulder is .441. In the AI version the the wall is straightened to a .445 OD whicl leaves .025 of taper. I'm not a smith or chamber engineer, but I would think that a straight wall chamber in rifle cartridges would lead to stuck cases, especially with warm loads. Hope that helps, Mark [/QUOTE]
