The side-by-side is definitely the way to go. If you're serious about a double just bite the bullet and do it, but don't cheap out an an over-under just cuz they are cheaper.
To me the way to go is a .450NE, .470NE or .500NE. Any of those calibers.
The Searcy's start at $16,000 and the rifle is an excellent well built rifle. I have read glowing reports about them on sites that discuss Africa and safari rifles. Their warranty is a "no questions asked" kind of thing. You pay the fees to ship the gun and the rest is covered.
I think the Heym and Kreighoff are probably as good as the Searcy, not sure about Merkels. I suppose all of those are on a par.
But for me it would be a Searcy, if I were buying a doubel rifle today. Sure a British rifle would be better, but the Searcy's are awfully good.
I also think the best action is the boxlock. I have just finished reading the chapter on double rifles, in Terry Wielands book
Dangerous Game Rifles, which btw, now that I have given it a second read is very good.
Someone mentioned the problem with the over-under and it is the action has to move much more on opeing/closing and consequently they are much slower to load and are not as strong. Which is why they are pretty much topped out at calibers like 9.3x74R.
Having said all that, I am a magazine rifle fan. I doubt that I will ever get a double. I have 2 excellent safari rifles already, a ZKK-602 in .416RM and a CZ-550 in .458 Lott. It is my intent to hunt with and become proficient with both of those, for that day when I might be able to afford Africa.
