[QUOTE="Clark, post: 926605, member: 6600"] SAAMI chambers are .220" to .227" for 300 Win Mag, 7mmRemMag, 338 WinMag, ect. I have never found any 300WM, 7mmRM, nor 338WM brass longer than .215". So I chamber my belted magnum rifles for .215". Most factory rifles are much closer to the SAAMI min of .220" than to the SAAMI max .227". With the exception of old Glock 22 40 S&W chambers, most ammo and factory chambers are at the small end of the wide and sloppy SAAMI tolerances. 303 Brit is the sloppiest [headspace for rim + rim thickness]. 260 Rem is the tightest [neck diameter of chamber].
