[QUOTE=kiwijames;508890]243Win has better brass options. Does anyone actually make 6mm Rem brass anymore?
A bigger powder load pushed through the same dia hole is faster....... but barrels are longer lasting? .............really?
Do some research the 6mm Rem has a longer neck it contains the burning gas better and protects the throat from erosion my 6mm has fired 3000 rounds and is still accurate
not many .243's get to half that, I was not talking about availability of brass or ammo just the merits of the cartridge, Winchester and Hornady supply both brass and loaded rounds
stand twist in both are now 1:9" the 6mm always was it took the industry a long time to figure out that the .243 should change.
