Reloading for a wildcat cartridge is not a beginner's game. That said, if you take your time and stay safe it can be accomplished with a couple of stepping stones.
I would start by buying a book or thirty on the subject and buying a rifle that is a bit easier to load for, like a 223 Remington or 308 Win, possibly a 30-06... There is a ton of into out there for these cartridges and that helps a bunch. Think of it as putting training wheels on for a few weeks before you get the keys to the Ferrari...
I would get a decent amount of gear... a press, scale, priming tool, etc... I would refrain from dropping coin on tools you really do not need to start with, like a progressive press or a run-out gauge... If you want to dive deeper into the game after you get your feet wet, by all means, but to start with keep it simple.
As to your stock... look around... someone is always selling the toy they decided they really don't need to fund the toy they now do "need".
