I'm not too excited about this one, I am a fan of 7mm for long range shooting, but I could give 2 ####s abouts belt/non-belt, makes zero difference to me.
The 175's I can shoot in my 7mm Rem with 1/9 twist provide a high enough BC for me for the 1000m stuff if do, and long action vs long action. Brass is easy to come by 7mm Rem, I got into the 6.5prc train, and it's decent, but I'd still like more powder room for it, and brass is sketchy to find, I'd rather not have to run max psi every boom to get the stated velocity either.
Hornady does a good job of providing factory ammo for their stuff, but I don't shoot factory ammo ever, this is their marketing scheme, they like to suck in the non-reloaders to these new chamberings, but it doesn't do much for the loaders.
As a loader, the best cartridge they put out is the 6mm Creed, everything else is pretty much redundant.
