[QUOTE="Danny1788, post: 1254555, member: 19965"] I agree 100% most of the time they are pretty close to the .550" of the ultramag case head, I have done a 6.5saum, and a few 28 noslers on mag actions. Sometimes the fatter case fits just fine other times it only needs to be filed/stones to let the case pass through the feed rails. The biggest change to make it work is upfront by the feed ramp into the barrel. On the mag actions the feed rail tapers into the feed ramp on a ultra mag action its wider to let the fatter case pass through. [/QUOTE]
