Not sure, since I've never seen one in person, but that's supposed to be 6mm USN on the bottom of the picture and it sure looks like a true rimless to me. FWIW, .220 Swift probably had its rim made larger than the base so Winchester wouldn't need to add another bolt-face size to their rifle production. Swifts normally headspace on the shoulder, not on the rim as a "real" semi does.... ]]> feeds@yuku.com (Parashooter) http://parallaxscurioandrelicfirearmsforums.yuku.com/sreply/193348 Mon, 15 Jun 2009 22:40:57 GMT http://parallaxscurioandrelicfirearmsforums.yuku.com/reply/193347/t/6mm-USN.html#reply-193347

6mm Navy is basically a .30 Army necked down and made rimless.

Quickload predicts about 2600 fps and 37,000 psi with 36 grains of IMR4350 and the Speer 105 RN, based on a case capacity of 51 grains H2O. Wouldn't want to go there without working up very carefully.
