I havent found anything that Ballistol is best for. Maybe being a jack of all trades.
When I was shooting a flinter, Ballistol and water were all I used and kept it spotless. Learned about it reading Ross Seyfried. He shoots a lot of BP, often in valuable vintage guns, and it’s what he uses. Flushing with a 4-1 water/Ballistol mix, followed by drying and swabbing with straight Ballistol works very well. Always pays to check the bore from time to time, JIC.
Ballistol won’t harm wood, or any finish IME, unless you really soak it.
