I think you should. I came late to the party and got my 6.5CRDM last year for Christmas. So for me, it's a nifty new cartridge. I have a .308, a 6.5 X 47 Lapua and a 6.5-284 and scads of other rifles. I certainly did not need the Creedmoor but let's face it, I would have been an irresponsible jerk if I did not get one.
At the risk of getting flamed, I'll say that I find it amusing how there is all this controversy over the cartridge. It seems to work very well, but somehow suffers this stigma of being passé because "everybody and their brother" has one. Sorry for the goofy analogy but it reminds me of how everybody hated Jeff Gordon in the late 1990's (guilty as charged). That didn't make him any less of a great driver. So, I'll keep my 1/2 MOA 6.5 Creedmoore and keep piling up whitetails with it. Let us know which one you get!
