The fact we call it bullet lube leads way too many to assume that lubricarion is the key. We actually need little, if any, actual lubrication. Matter of fact excess lubricarion is detrimental to accuracy is almost every instance.
Only one way to know what lube is going to work in a specific situation, that is by testing. We have found lubes that are awesome in a handgun yet horrible in a rifle.
Not sure how many here know what the 68 in SL 68 stand for. It is the 68th major lube test in the soap lube series started by Gear. Many have had sub-lubes made with minor tweaks.
