[QUOTE="SDMF, post: 189188, member: 412"] MOA, assuming 1/4MOA increments of internal adjustment, you only ever "count" to 3. Get to "4" and you're at another whole number. Mil-Dots in a 2nd focal plane scope on it's LOWEST power setting are generally 3x more than their designated/calibrated "X" setting on a power ring. IE: SFP scope, 3.5-10 w/Mil-Dot calibrated for 1Mil @ 10x. Each Mil-Dot = 3Mils @ 3.5x, now you're getting pretty close to a good "lead" starting spot for running vermin. Livetohuntandfish, the big appeal of the 6.5Creedmoor in particular is that it's one of the 1st chamberings in which std bbl twist, chamber geometry, and magazine box constraints were all considered AHEAD of time. Right from the get-go they have enough twist to shoot bullets from the newest generation of R&D. Those bullets are easily housed within a factory offered internal box magazine with enough space left over for a bandleader to jam the lands, and a volume shooter to chase them. For the reloader and.or volume shooter, the 6mm and 6.5mm make financial sense because the bullets are just plain less expensive. My 243AI costs roughly 60% of what my 308 does every time I pull the trigger with the bulk of that cost differential housed within the projectile. "Good" .308 diameter high BC bullets are going to be .35+ cents each. 6MM high BC bullets are in the low .20's. No biggie if you're shooting 2-3 boxes of ammo/year. Much bigger deal to the guy going through 2K-3K (or more) bullets/summer. Recoil is also a factor. I know 50rds of 155gn 308's from a 10# rifle in an afternoon will give me a headache. Add a little weight to the rifle and neck it down to 243AI and 50rds is barely a drop in the bucket of recoil toleration in a given afternoon. [/QUOTE]
