I gave up on messy lubes after discovering about under the ball wads.
Especially when articles on the subject of crossfires explained how loose primers can be at fault.
Mostly now I use a dry wad made of automotive gasket paper cut to a suitable diameter.
Or commercial lubed wads when available.
I've read that some folks just use cardboard even.
The real trick, though is abandoning black powder for the clean burning Hodgdon 777.
So much better with rarely a complaint from the smokeless crowd.
Making sure the primers are a good fit, too, hasn't led to any crossfires.
For general lubrication, the usual suspects do nicely.
For arbors and cylinder pins, a occasional wipe down with a lubed rag seems to do well enough for a range day.
Of course, if you're a die hard black powder fan and don't actually mind the smell of rotten eggs and getting dirty looks, there is one advantage.
Clearing out a crowded range quickly.
