I'd suggest you go out and buy a couple of books on it.
You'll need the reloading data. Figures pulled off some random website may be inaccurate and unsafe.
If you do opt to reload, expect to dish out at least $500 for equipment. I don't know how much shooting you do, but I don't get the feeling that you shoot enough now to justify the expense.
$500 will buy a fair number of shotshells, your time has some value, and shot primers and powder aren't free.
