I don't mean to sound disrespectful, but you can spend a mountain of money on that rifle and it won't be worth one cent more than it is right now when you're finished. Some of the worst Mausers ever built in terms of quality of workmanship were the Spanish Mausers. Back in the heyday of sporterizing military rifles, the 50's, 60's, and 70's, even the Spanish '98's (La Caruna) were regarded as being at the bottom of the heap and not worth sporterizing. Their reputation as really crummy Mausers go back even as far as the 1960's.
You have what is basically a weak 1893 Mauser action without even a bolt guide, only two locking lugs turning into a soft receiver, a cock-on-closing bolt, and a striker fall that's a mile long. In order to use it with any of the rounds you mention, you'll need to have the bolt bent for a scope plus having to drill and tap it for mounts, and then you'll need a better trigger and an entirely different safety setup to realize anything like its potential accuracy. By the time you rebarrel, restock, retrigger, resafety, and refinish your rifle, you will have enough money in it to afford a very good if not premium factory rifle, and all you will have is a rebarreled, restocked, refinished crummy Spanish Mauser. Also, often the 1916's have been shot out and the firing pin hole in the bolt needs to be drilled out and shimmed which is a machine shop operation, and only if you can find the threaded shims it takes to do the job. (See if the firing pin has space around its circumference when it is uncocked. If so, big waveoff.) If you should find that the hole has already been shimmed, and it's very visible, you'd be money ahead to hang it on a wall because it's well on its way to being worn out the second time.
Sir, with all respect, I'm 72 years old and I dinked around with Mausers for a lot of years, sporterizing a great number of them. I know this is hard to hear, but again in all respect, I would advise you to save your money and find yourself a good Swede. Your Spanish Mauser is a colossal disappointment looking for a place to happen.
