I have a buddy with over 100 handguns. He shoots a lot of magnums. 44 mag, 460, 475, 480, 500, and probably a few more wildcats.
He says his favorite is the 480 and for how much power it has it shoots like a dream. Accurate, low pressure, etc etc. He went on for about 15 minutes about how it was the best once.
I didn't buy one b/c ammo is expensive and not as available as 460, 454, and 45 colt.
