The 6mm/.284 sounds like a great round but it is too long. I'm looking at the Howa/Christensen Varminter, Tikka varminter, and the Winchester Coyote lite. And they don't come in that caliber and it would probably be too hard to rechamber one. So I'm thinking the .243 Win and then blow it out to the Ackley Improved. What do ya guys think??
