Ok, I have my primary elk gun ready to kill elk. Now my backup gun is my .308 and she's a shooter. Consistently shoots 1" groups at 200m. I have her dialed in on two loads. 168 gr nos ballistic tip and 180 sst. The 168 gr has a muzzle velocity of 2700 and the 180 gr is about 2800. Neither bullet is my first pick for elk, but the lower velocity makes me think they would be fine out to 300. Thoughts?
