Reading iofthetaiga's "Am thinking of building a custom" thread, got me to wondering. If you were building a 6.5 mm rifle from scratch, which cartridge would you select and why?
The 260, 6.5X55 SM, 6.5 creedmoor, or the 6.5X284?
Would you want a short action or a long action? What bullet weight would you build the rifle for, and which barrel length and twist would you chose?
