Ralphie and Szihn both mentioned bullet choice for magnums. For whatever reason I’ve had some very close shot opportunities for elk, and if I’m shooting a bullet faster than about 2900 or 3000 fps I want a tough bullet, Scirocco, Accubond, Partition, TTSX, others etc.

Below 2900 fps more bullets work well. I still prefer heavy for caliber.

I’ve killed elk with a 30-06, 50 cal muzzleloader, and 7 Mashburn. They all work. If I had to pick I would pick the Mashburn because I have 2 that I really like.
