Hand loading isn't something folk should just wade into without some degree of knowledge but it's not that difficult and done properly it's not dangerous either. As others have already said, read up on it first and learn the basics. I find the Lee book very good as a starting point. He sells his own kit pretty strongly but also gives some good information. Any reasonably intelligent person can load ammunition. As for making your own bullets, I guess if you are skilled enough to run a lathe to that degree of accuracy then why not? It may be easier though to specify a design for a lead bullet mold and have one custom made. Casting bullets is much easier and faster than turning them and you'd be amazed how well they turn out once you get the hang of it. I cast for my .45-70 and .357 lever guns and have just got a mold to make bullets for my .416 Rigby too. Although not ideal for dangerous game, cast bullets are great for firing at the range and allow you to get a lot more rounds down range for a fraction of the cost of factory ammunition. Hornady rounds for my .416 cost about £6 each here in the UK. Using bullets made of scrap lead and brass from shooters who don't reload I can get that price down to around £1.50. Quite a saving!
