To the OP...
You said you don't hunt and don't shoot competitively, so I'm going to throw a monkey wrench into this discussion by enlightening you to another option: a fast twist .224 caliber that soo many dismiss or overlook due to ignorance. A good fast twist .224 caliber shooting sleek high B.C. bullets will do anything a 6mm can, and often times do it better. Obviously I'm not talking about a .223 Rem based cartridge here, but something akin to the .22-250 Ackley Improved, .22 Creedmoor (basically identical to the 22-250 AI in terms of capacity and efficiency), a shortened 22-284 Win. wildcat, the 22 BR, etc. Basically something with sufficient case capacity to push those 80-90gr pills to 3200fps or better.
Just as a personal example, I've been shooting the 22-250 AI with a 26" 1-8 twist barrel since 2004. With a stout charge of H4350 propelling an 85.5gr Nosler RDF. bullet to 3,250fps @ muzzle. With a 200 yard zero I only need to dial in 6.4 mil of elevation, and while the 22 caliber bullets will be affected a bit more by wind, given the aforementioned setup with a 10mph crosswind it's still only 2.0 mils of windage. Comparing that to the 6mm Creedmoor pushing a Nosler 105gr RDF at 3050fps with the same 200yd zero, you would be looking at 6.8 mil elevation and 1.9 mil windage.
So the 22cal has a slight advantage in drop and the 6mm has a slight advantage in wind, but it's basically a wash. Both cartridges in this example use very similar charge weights of the same powders so that's pretty much a wash as well. Where the 22cal has a bit of advantage is in recoil and cost. Granted the difference in recoil isn't substantial, but it's there. On the cost side, 22cal bullets are notably cheaper than the 6mm bullets - and MUCH easier to find since everyone and their brother is currently on the 6 and 6.5mm bandwagons.
While these faster 22-caliber cartridges are often labelled as barrel burners, I've been shooting the same Douglas barrel for 18 years now and have run just over 2000 rounds through it to date. Last time I had it out and shot a group at 200, it measure just a hair over 1/2 inch, or 1/4 MOA. Don't have a pic of that specific group, but I'll include one of a similar group shot in 2018 with said rifle with 80gr Nosler CC's.
Yes I'm probably overdue for a new barrel as the bore looks like alligator skin for the first 4-5 inches at this point, but the dang thing still shoots!!
