I am just curious to get some feedback from some other hunters on this topic. I am going on an Elk hunt this year and I will be loading my own ammunition, as always. I will be shooting a Model 700, 300 Remington Ultra Mag. The two bullets that I am considering for this hunt are the Sierra Gameking in a 180 grain or a Nosler Partition also in a 180 grain. Any feedback would be appreciated.
