That's a tall order..
I'd start with a small cast iron Dutch oven and a turkey fryer to melt my lead/ wheel weights in, and something to use as an ingot mold to pour my melted alloy in. Lyman makes a good one, but an old cast iron cornbread mold will do just as well. You'll need some sort of skimmer to clean the trash from your melted alloy, as well as a tiny bit of paraffin or wax to flux with. I use an old soup ladel to get my melt into my ingot mold.
BE SURE TO KEEP ANY LIQUIDS AWAY FROM THE MELTED ALLOY!!Now to casting...
I have two Lee pots, and when they get adjusted right, leakage isn't an issue.However, if you think that you'd rather have an RCBS or Lyman pot, feel free. I prefer the bottom pour pots, but some prefer to use a dipper. Get a good dipper, not a Lee dipper. For molds I have both Lee and RCBS. Lee molds come with handles (unless you get the six cavity molds) and I don't know of any others that do. With care Lee molds will last for years. I've yet to break one or wear one out. I just don't like Lyman molds...All but two of my pistol and revolver molds are plain base molds, and I don't have problems with leading. I have two rifle bullet molds, both are Lee and both use gas checks.
Lee makes a good sizer that you can use, and it's cheap,but I find it a bit messy. The results are great, so a bit of mess isn't a problem. I also bought an RCBS LAMII and a heater for it. I also bought RCBS sizing dies and top punches, altho Lyman sizing dies and top punches are interchangeable. I like the RCBS warrenty,and have made full use of it.
For bullet lube i've used Lee Liqiid Alox, the green stuff RCBS puts out, a few different tubes of whatever Lyman offers, and some stuff that I made myself. Then I tried some Lars caranuba Red from White Label Lube and haven't looked back. it's about half of what you'd pay for similar stuff at Midway or wherever, and works great.
A cast bullet handbook by Lyman would be your best bet for info and other things that I know I haven't mentioned, such as a hardness tester. I think Cabin Tree sells a good one, but I don't have one, so can't comment on that.
You'd be well serverd to peruse the cast bullet forum, too. There is a wealth of information to be had there..
