I know a few guys that can show you consistency with 6.5 Creedmoor at a mile, in Florida. On a full sized IPSC plate. Sure, not every shot is a hit at that distance, but you would very much be surprised to find out that they impact more often at a mile than most do with the big boomers. No shit!
Anything is easy if you use a big enough gun, but it’s way more fun when using something that most people, apparently yourself included, don’t think is capable.
As far as ‘real world’ goes, that’s an ambiguous term that could mean anything and has no bearing on the subject.
Now, is it a practical use of the caliber for hunting or anything at all except fun range time? Well no, of course not, but was that even the discussion?
Oh, and yes, they shoot and impact regularly at 2000 yards, with the 6.5 Creedmoor also. It’s not rocket science, it simple ballistics.
