Look forget the hollow point tools and conicals. Start shooting using a Patched Round Ball( PRB). The balls are cheaper, lighter in weight, and accurate out beyond 100 yards, which is as long a distance as you want to hunt using open sights. Its takes practice to hit small targets or shoot small groups at 100 yards, even off a rest. Lots of practice. you will get much more practice shooting PRBs than if you shoot those conicals, which will rattle your teeth until you learn how to hold the gun right.
You are at the bottom of your learning curve, and you don't even know what you need to learn. Go to the Links sections here, under Member Resources on the Index pages. It will take you to a long list of suppliers. Most have on-line catalogues. Look through them. If you have a local gunstore that caters to BP shooters, visit it. If not, try to attend a rendezvous, or your Texas state BP Championship rifle matches. Guys like Rabbit03, or Davey, or John Hinnant, all good Texans, can tell you details, and are members here. The suppliers who work at those large shooting events, and the men and women who are shooting there, can help you find and buy the stuff you need.
I recommend the Tedd Cash adjustable Powder Measure, that has a funnel attached to it to help you get the powder into the barrel, for instance.There is also a Nipple pick, or wire, attached to this powder measure, located in the bottom of the measure, you can use to mechanically clear a clogged nipple. There are other adjustable measures you can buy for less, but the cost on this one is worth the extra money.
You are going to need cleaning jags, a Range rod, a patch pulling jag, a ball pulling jag, and a bore brush. You want to buy only jags that have steel threads on the brass fittings, rather than those made entirely of brass. They may cost a dollar more, but its money well spent.
You also need a nipple wrench, to remove the nipple for cleaning, and for replacing it.
You need pipe cleaners in your range box to use in cleaning flash channels, and drums.
YOu are going to want to try different thicknesses of patching material, from .015" to .020" with a .490, and a .495" diameter round ball, to see which your gun shoots best.
You will use different lubes. There is an article in Muzzle Blasts, the monthly magazine for the NMLRA, last month about lubes, indicating that some lubes work better in some guns than others, and each gun has its own preference. But, using the right lube can reduce group size in half.
