Hello I'm new here and this is my first post. I'm in the process of building a custom long range rifle chambered in .308 Norma Magnum. I'm trying to find the ultimate long range bullet that has a great BC, amazing terminal performance, and able to make kills on elk out to 1000 yards. I have looked at Hornady's 178gr and 208gr AMAX and really like the 208 but think it may be a bit too heavy. I have a few boxes of 190gr Sierra Match Kings that are more of a target bullet but my uncle has killed mule deer and elk with them but I don't want to chance it. I'm really wanting the new Nosler 190gr Long Range Accubond bullets but on Midway's sight they keep saying that they're coming soon. So thats why I'm asking you guys. My rifle is nothing high tech just an old Model 1917 Enfield action that I'm putting a 28" Hart stainless barrel on with a 1:10 twist and a #4 contour, Leupold 6.5-20x scope, thumbhole stock, and a cock on open kit and Dayton TriStar trigger. My uncle and I are working on it right now and its mainly going to be used for deer, elk, and varmint/predator hunting out to 800-1000 yards but able to be carried into the mountains without having to wheel it around on a carriage haha.
