If you are going to be doing any prone shooting, I would get his solid bottomed brake, not the full profile radial (Holes all the way around it).
Good that you looked at a total package: scope base and muzzle brake.
Hopefully you were looking at the picatinny/Weaver type base. Right?
My current MOA cartridges are: 6mm-284, 6.5x47 Lapua, 6.5-284, and 7mm Rem Magnum Improved.
Here is a friend's MOA in action, that I used this past fall. 14" 308 Win using Hornady TAP ammo (168 grain A-Max).

I always give my friend a hard time about the 308 Win as a LR cartridge, so when I said I would use his MOA, he definitely had to catch me on film using a 308
It is a good cartridge, but it will come down to what you want, not what I use or want.
Wow nice stuff. Looks like about $1300 should get me out the door with muzzle brake, "0" MOA base and shipping.
