Not having the ivory would be tough, but Mozambique sounds amazing. Is the law that you cannot import ivory from Moz?
The current USFWS rules are a case by case basis. The simplest way to explain what it takes to get elephant ivory imported to the US is that by you hunting said elephant, it results in an enhancement to the survival of the species in that area. This is accomplished by the outfitter doing things with the money to improve the elephants situation. Such as convince the locals to not poach or poison elephants. Enhancements to the environment, etc. Theoretically this can be done almost anywhere including Mozambique.... The Outfitters just need to get on board and document their efforts. And convince USFWS they are doing this and getting results or at least making an all out effort.
Be careful you don't fall into the trap of an outfitter telling you an elephant is exportable. You need it to be exportable from the country you hunted (it may not be), as well as IMPORTABLE into the US. Seperate but connected issues. This is why a conversation with Conservation Force or Safaris Specialty Importers well ahead of time is a good idea. As mentioned, Conservation Force takes a proactive approach and are expensive but get the job done. I've had good results with SSI importing a lion from Tanzania, which is considered the other really tricky trophy to get imported.
There is lots of info on this site regarding all this. It takes some research and reading. Realize this all changed regarding elephant imports after Obama banned imports in 2014. Then Trump Tweeted to illegally stop the process during his first term. Conservation Force sued and got the process reversed back to the Case by Case basis. A side note, SCI complicated that process... the Conservation Force folks can fill you in....
The rest of what you need to do is to be on good shape to walk many miles per day through difficult terrain. Hold your nerve and know your shot placement. Have the ability to make the the shot and follow up. If your elephant drops head first, get another shot into the top of the head immediately and one through the chest isn't a bad idea. This is because you likely missed the brain and stunned it. You knocked it out so it's going to wake up and run away. If it tosses it's head up and the rear legs collapse first, you most likely brained it successfully. You probably know this all already if you've watched enough videos.
Then the most important part.... As eluded to by
@dogcat1
Know what you are doing. You are killing an intelligent being that seems to have intense feelings and is quite intelligent. It will kill you given a chance, as will it's herd mates/family. It is also likely as old as a middle age human. Hunt it with the respect it deserves. Have your head straight about this. If you are doing it to square off with such a beast in it's environment and achieve an accomplishment, you are fully prepared, and know that doing this will enhance the species' lot in this World... By all means charge forward with the endeavor
It is a grand mix of emotions, at least it was to me.
And yes we have all been saying to do it sooner rather than later as we have no idea how long we will be able to hunt these magnificent beasts.
