I have found it to be quite funny over the years the differing opinions towards a new rifle cartridge being brought to the market place. I've only been shooting rifles for about 46 years,and on almost every firearms forum on the internet there is at least one thread complaining about the 6.5 Creedmoor's popularity.
I happen to really like the 6.5 Creedmoor,and have been shooting it since 2009. It's a great cartridge for almost any type of shooting,it has good speed,a great selection of bullets to choose from,can be loaded with a bunch of gun powders,and is accurate with almost any combination you try with it.
I've built 4 of them,as well as my latest chambered in 22 Creedmoor. I have never shot any factory ammo out of mine,so I can't comment on how they shoot with that.
The 6.5 Creedmoor isn't a miracle cartridge,it does things better than some,and worse than other's depending on what the shooter/hunter is trying to accomplish. I target shoot out to a mile with mine,and also hunt hogs,coyotes,and deer with them. For larger game,I choose to use a better cartridge,I'm not saying the 6.5 Creedmoor can't do the job,I just have many other better choices to pull out of the safe that work better on elk,moose,etc.
Then you have the crowd that tries to claim the 260 Remington & 6.5 x 47 Lapua is better than the 6.5 Creedmoor. I'm sorry,but they are all so close in every category of shooting you can throw out there.I shoot a 260 Remington in a DPMS large frame AR,and built a 260 AI bolt action also. Other than the 260 AI having a velocity advantage,it isn't any better,my 6.5-06 will beat anything it can do with the same bullet..
We,as shooter's are lucky that we all have the choices of cartridges today to shoot. If you don't care for the Creedmoor family that's just fine by me.
Shoot what you like,and quit complaining about the 6.5 Creedmoor!
