I am currently getting everything setup to start reloading for my 308. I am also looking at loading a bullet that would be great for both deer and elk sized game. I have been looking at the barnes tsx and the nosler accubond, both in 165g but I'm not sure if I might need a 180g for elk sized game or not. I am putting in for elk for the first time this year and if I get a tag, I would not want to waste it on the animal getting away. I hate losing an animal that I have shot. Any help here would be greatly appreciated. Also the reason I am looking at just sticking with the 165g, and not loading 165s for deer and 180's for elk is that way I don't have to keep re-zeroing my rifle, unless this is what I will have to do.
