Not sure if this is the correct catagory, please move if not, thank you. Could the experts please school me, the .50AE like from a Desert Eagle semi, how does that compare to a 500 S&W for say hiking in Alaska and protection against really big bear? I understand your proficiency with each gun and the right ammo in each of the guns could mean all the diffrence in the world, but just in general. Are they both equally capable? Thank you.
