Short answer, I agree with Randy on this one...
I bought my first flintlock in 1977...We didn't have Bore Butter back then...The first time I heard about this "seasoning" stuff was in their ads...Previous to this, I had used several different lubes and had settled on SnoSeal...I used to compete with a custom maker that has had his flintlocks win at Friendship...He used axle grease as a patch lube...
I tried Bore Butter as a patch lube and found that the patches burned out with higher charges in my .54...
You've had a cheap lesson in Marketing 101...
