The best place to start is to read a reloading manual, such as hornady or sierra (my favorite bullet companies). Not only do they have data for their proprietary bullets, but they also have a ton of information that is useful to the everyday hand loader. Not that I'm trying to put you down and I mean no offense, but it's funny that you mention using heavier bullets for better accuracy. When I got started I knew next to nothing about shooting or reloading, but this forum, the manuals and a good friend have all taught me a lot these past years, and I remember having the same sort of thoughts on shooting, only to find myself corrected.
Good luck, and keep reading; there is a lot of information out there.
