Why don't we just say that the difference between a 270. 280 Ackley and a 7RM is basically the same, up or down. I'm a reloader so you might as well add the costs to reload each if discussing all the merits. 280 brass is cheaper than 7 mag and in a pinch you could use 06 brass as well for the standard or Ackley version of the 280. Less powder, recoil, muzzle blast and usually packaged in a light config make the 280 Ackley more attractive to me than the 7RM. Unless your ammo doesn't make it to your destination for some reason (and everything it was packaged with) ammo availability is a non-starter for me. For me, it's the sum of little gains that make the whole package more attractive than either the 270 or the 7RM. Won't argue the paper ballistics cause that's all that it is, paper and arguing.
