I'm not real big on telling folks how they should do stuff, as I've always seen that there are lots of paths that lead to the same place. Having said that, it just makes sense to me that if a body wants to shoot any kind of distance at all, just learn to do it right, and go on with it. Sure there's some investment in it, but it doesn't have to be ridiculous.
You will need premium ammunition, hand loaded is best, but that doesn't mean you need to dive into hand loading head first. You can seek out and make friends with someone who loads, and get them to mentor you on their equipment. Or there are several places now where you can buy hand loaded ammo commercially. It won't be loaded with all your gun's distinct tastes, but it will be much more consistent than factory ammo.
You will need access to a chrono. Again, make friends with someone who shoots a lot, or most any hand loader, and they'll probably have one. In all the ranges I've been to, I've only ever seen one that rented them, but it I'm sure there are others that do. Then there's always ebay, or clearance at midway...they aren't terribly expensive, and the information they equip you with is critical.
Spend some time learning MOA (or mils if your into metric), there are books, and countless articles and tutorials around the internet. The basic concept isn't hard to grasp, and once you do, it's just practice from there.
There are a bunch of ballistic apps out there for whatever phone you have, and once you have all the information they require, they aren't hard to run. Go to the range, and confirm everything and practice...it's fun! There's no reason to make elevation hard, with just a little work it's not hard. Wind, well wind is hard as hell, but you can do elevation if you really want to.
