i use a 1:10 ballistol & water solution for both muzzleloader and bpcr fouling control. when i'm done shooting at the range or field, that 1:10 solution of ballistol & water protects during the ride back to the ranch, where all that's needed is plain tepid tap water to finish up the cleaning, then a final patched jag with pure ballistol to preserve. the fact that ballistol is non-toxic and is compatible for use with so many other materials and components is its exceptional value.
