Now, if I only had a neck/throat reamer for 6.5, I could make up a 6.5/220SwiftIMP chamber using my .220 Swift IMP reamer. Now THAT would be super - or about identical to the .260 REM/6.5x55 line of ctgs. as 55gr. total case water capacity.
It WOULD certainly be a different case, though. LOL New and improved.
