My humble advice is enjoy the hyper fixation and try to remain excited, but defer ordering a brand new double that’s 65-85k British pound sterling with another 10k in the oak and leather case, which you’ll find is well north of $130k US by the time you have it in hand…for one barrel let alone two...at least until you can make said purchase with even the most remote idea of what you like, don’t like, need and would plan to use it for.
I love these threads because they are so much fun and so exciting for many people participating, but as the first page shows you, no single person can answer your question because only you can know and truthfully only you can know through at least some experience. That doesn’t mean you have to go on X number of safaris before buying a double, but before you can make an educated decision on buying a double you may actually like, maybe even keep for a bit, possibly even take to Africa and hopefully not have it prove a miserable experience and loose your tail end on, you have to gather some basic ideas of what you like and don’t.
Again, just the first page, you learned you should get a 500NE and bolt gun, a 470, a 500 and 450/400, and maybe not even a double at all. Every one of those are sound pieces of advice for each of their experienced tastes. What double is almost as personal as what kind of underwear you like. So love this and have reason, some others, and the double crowd can prove a fickle bunch. That is why you will notice certain doubles fly off the market as soon as they appear if not well before and others sit in the market place languishing for months and years even.
All that said, I was very similarly situated to you not all that long ago. Since then I’ve owned 13 doubles, working up hand loads for regulation one each of them except one, a new 470, that went to its new owner and fellow forum member directly after I imported it with my most recent 500NE. I had planned to keep it at least long enough to play with it some and work up regulated loads, but knew I wouldn’t want to keep it long term and I’m simply not a rich man where I can afford to keep all the guns I like.
I see the adventures down this path of double fever as going one of two ways, buy smartly and with a little patience and you’ll learn a lot, have fun, fall in love, and if not, move on relatively unscathed. Buy hastily, and the path turns treacherous rapidly, with long hours of despair, additional lost money and time fixing unknown issues and fitting problems and things you don’t like and didn’t know how much so until you carried and used the rifle for a while. And then take a big clobbering when you try to pass along that gun, hopefully with full disclosure if any issues you haven’t properly fixed.
So much excitement, rewarding times and danger ahead. Like the saying of envy for the man who has not yet ventured to Africa for he has yes so much to see….I also envy…that sir is you.
