I went back and forth for awhile between accurizing a factory rifle or going with a fully custom weapon for just that reason. By the time you are done upgrading your rifle with everything you want, you might as well have just gone fully custom. At the end of the day I opted to just go with the factory Sendero and spend my fun money on a cool hunting trip. Truth be told, my gun was shooting sub MOA at 100 and 300 yards which for the first twenty rounds out of a brand new rifle and shooting Rem Core Lokt, I was happy with. I've been a .308 shooter all my life and once I really get a better feel behind that new .300 Win Mag, and I find ammo she really likes, I can only expect it to get better. My last three rounds we moved back to 650 yards and I shot a (3shot) 2" group, all in the black on one of those Shoot N-C 8" targets. As a hunter that is exactly the performance you want to see, and definitely gives me a lot of confidence in my equipment. Still a lot of practice to be had, but definitely a great start.
