My opinion, if you're going to go with a 6.5-06, you might as well go 6.5-06 AI. And if you're going to build a 6.5-06 AI, you might as well build a 6.5 Sherman to get ALL the velocity possible out of that case. See "elkaholic" (Rich Sherman) on here for more details. He has reamers for rental, and dies available for purchase.Hi guys, maybe some of you fellas could tell me whats the advantage of the 6.5/06 over the 6.5/284 if any. I'm thinking about building a 6.5/06 but I can buy a 6.5/284 already built, just considering which way to go.
