I know one PH who has a reloading bench at his base camp. This is the obvious way for a hunter who is coming with several calibers and can't get under the airline weight limit. Empty brass and bullets don't count in the limit. Bring your 416 Rigby or 404 Jeffery dies and study the Sonchem tables before you go. The PH can probably make sure there are the right powders, some primers and some Rhino bullets to experiment with as well. You can always find the time to load a few, instead of sleeping for instance.

I think this is a wonderful idea.

This sounds like a great idea.

I'm not sure I would take advantage of it as I've seen the effects of using different lots of the same powder on pressure...this goes for different types of primers also.

I don't load my ammo to the max but I am pretty fussy about how I assemble it...I'll stick to making my ammo and checking it twice before I get on the big bird....it's part of the ritual of getting ready to go.

A great idea in some places, but last I heard in Zimbabwe they call it ammo manufacturing and it is very difficult to get a permit for. Ammo is very expensive to buy so I always bring extra 375's and 458's along. In my opinon a great idea otherwise. We should all keep our handloads well under the redline when hunting in warm climates.

It is definitely not feasible everywhere and reloading .375 H&H is not really the point as it can be found almost everywhere as well. But if you are going to RSA at least and like to shoot exotic calibers and can't carry enough of the loaded variety, it's nice to have the option. If you leave a few with the PH he will also appreciate it I bet. He can sell it at outrageous prices to the next victim of airline baggage handling expertise.
