Plus, a lot of good off-the-shelf ammo with very nice bullets. Again, great round there's a lot of smart people, a lot of good math, and a lot of tiny groups that can attest to the ballistics of the 6.5mm. 260 Remington, but the Creedmoor is the current hot thing with a lot of nice factory loads and off-the shelf barrel options). 264 caliber, which for an AR-10 would be the 6.5 Creedmoor (or the. Of course, that naturally leads the conversation to the.

308 projectile would need to be over 200 grains, which cannot be pushed nearly as fast when you're working with a. 308 match bullets and to match the form factors of some of the 162-grain. 284 hunting bullets that have BCs equivalent to 178-grain. Just flipping through one of my Hornady reloading books, I'm seeing mid-weight 154-grain. 308 service loads, I've found that the two cartridges have very similar muzzle velocity potential, but the more slender 7mm has a distinct BC edge. 308 loads with bullets in the 145 - 155-grain range typical of. I have a friend who's just getting into target shooting with a bolt-action, and I recommended the. 308 it's a great all-round, well-balanced cartridge that's relatively economical to shoot, easy to find, and gives a ton of options both for reloading and off-the shelf.

The planned end result is a really high-end AR-10 with a lot of nice features (perhaps even multiple uppers for different applications), so each step is probably going to be fairly expensive, and the final price tag will probably be intimidating. This'll probably be a pretty drawn-out build one major component at a time as I research things & make up my mind, and as funds allow. I ended up with a little more free money than usual thanks to some Christmas gifts, and when I saw that Aero had a good sale going, I decided to pull the trigger and kick things off. This is a project that I've been thinking about for quite awhile now, reading about AR builds and bookmarking parts & manufacturers that I came across & liked.
