My humble 2 pesos on the topic:
The 6.5 Creedmoor is the latest greatest flat shooting cartridge to make the scene in "affordable" platforms. It's allowing the average Joe to get into precision "long range" shooting for a moderate price, instead of the thousands of dollars it took prior. Right now you could could go out and buy a $500 rifle, a $200 scope and 100 rounds of 6.5 Creedmoor and be "on target" at 800 yards within a day of shooting. Not too many other platforms will allow that. I'm sure you remember when the .338 Lapua Magnum was all the rage, every tactical Timmy just had to have one, they'd spend between 5 and 10 thousand dollars for a rifle and scope and spend 2-4 dollars a shot for something they couldn't handle due to recoil. This 6.5 Creedmoor may not be the powerhouse the LapMag is, but it's certainly got accuracy on it's side. Those of us who have been around rifles for more than 15 minutes know 6 to 6.5 ANYTHING is going to be accurate, better yet, how about us old timers let the younger generation have their 6.5 Creedmoor, and we'll keep the 260 Remington to ourselves as our own secret weapon that'll outshoot that Creedmoor any day of the week.
