Thanks for the responses....here is the background on my question...I bought some 1/8 oz minnow head jigs (both I feel like came out of a do-it mold)...If there is any size difference you can't see it with the naked eye....one weighed 65 grains and other weighed 50...The lighter heads were a much duller color so I got to wondering if it wa a different type lead....

I'm using a small pocket jewelry scale that I know is probably not completely accurate but it seems VERY consistent which is all I'm concerned with...I don't care what anything ACTUALLY weighs but I'm am concerned with what it weighs in relation to the jigs that I learned to fish with.
