I'm preparing for a mule deer hunt on the kaibab and I have a cooper 92 backcountry in a 300 win mag. I'm currently dialed in with a 165 tsx coming out the barrel at 3200fps. I talked to the guide that Im hunting with and he is against me using tsx's and prefers something like a partition...has me thinking maybe I need to change and work up a different load?? I've harvested mature bull elk with 180 tsx's and had them drop in their tracks so I do have confidence in the performance of the bullet...Any thoughts???
