RE: 6mmx284 or 6.5x284???
Agood friend of mine had a custom 6x284 that he used for shooting at 1000yds and he had to say, although the gun shot very well it burned the barrel out in less than 1000 rounds. Should he have to do it over he would have went with the 6.5 instead of the 6mm. Now when I say he used the barrel up, I'm talking at shooting for accuracy at a 1000, it still would shoot fair enough for hunting purposes.
