RE: is bore butter necessary?
Bore Butter is not made for inlines, don't use it in them...Regular gun oil is what is best for an inline...
Bore Butter was developed for side hammer guns, they marketed it as a product that would "season" the bore and
give you many shots between cleaning...Most of us didn't buy it...We realized that while you can season a cast iron
fry pan, gun barrelsare made of steel...
