Mike take what ever Fun you are comfortable shooting, I switched from the Nosler Partition years ago to the Barnes TTSX, The nosler's would no group well for me.
Been traveling from Pa to Idaho since 1983 to chase elk. They have a strong desire to live and can take some lead, if you have the chance to shoot an elk. Shoot until his head is on the ground. And remember if it is public land, you will not be alone.
