Several friends of mine that have tried ..243 Winchesters have all told me that they got very low milage out of their barrels,some with as little as 2,000 rounds.
, got a question for you. I have heard about the short barrel life issue with the .243. Another rumor I have heard is that the 6mm Remington gives superior barrel life because of the longer case neck. The reasoning being the erosive high pressure propellant gases don't come into contact with the barrel as quickly as the 243.
Any truth to this?
