I went on my first elk hunt last year in southern Colorado.

I was shooting a 7x57 with fixed 6, my friend has a iron sighted Mosin in a ramline stock, and my other friend had a 30-06 with a 3x9.

We got 2 elk. There was no drama.

I will say that my friend with the Mosin is an exceptional shot. Far better than me, or almost anyone I know. That is why he uses iron sights.
