I know a fellow who swears by the Federal factory loads for the .470 Nitro. He has taken a couple of elephant bulls, three buffalo, two lions and the list goes on. They certainly seem to be working for him. I have had good luck with Hornady ammo as well as reloading components. I started reloading a few months ago and love it. It has allowed me to become proficient with my heavy caliber rifles. I doubt I would have practiced as much if I had to buy retail factory ammo. Another perk is that I found a load that works very well in my .458 lott, and with a bullet not available in any factory ammo without having it custom loaded by Superior or one of the other custom ammo providers. That bullet being the Swift A-Frame 500 grain soft point. A bullet well worth the trouble to have for dangerous game. I havent looked back since starting to reload. I recommend it highly. It would be nice to know someone who has some experience to help you get started. It should be easy to find someone willing to help. To facilitate my focus when reloading (particularly for use on dangerous game) I ALWAYS turn off my phone, turn off TV and put the dog out so I can give my loading undivided attention.
