Bakes,

Looks like our friend forgot about this topic...

If you use a proper lube you won't have a problem. Crisco will work (lard) but runs when hot. You can solve that problem by having an overpowder felt wad. You can cut these from old felt hats you pick up at boot sales. Lots of shooting out of one hat. Some lubes don't run in the heat, your BP guru will know which ones are available there.

RB isn't necessarily more accurate or more accurate at a given range. At the ranges you're discussing, 5-20 meters, you'll have plenty of accuracy! Heck these things were used on men to 300+ meters!! If you want you can even make paper cartridges, there's websites with complete descriptions of this.

BTW, these will do a number on hogs. Take your favorite shot and enjoy your meal.
