i know this maybe should be under the lube section of the forum but am hoping to keep it here where the black powder buff's are for answers.
i heard that a 3 part mix of equal parts bee wax, vegi crisco, peanut oil would come close to approximating the recipe for SPG.
i used a wax/crisco mix with just a couple tablespoons of peanut oil so i added more peanut oil...[to what i supposed to be a 1/3rd for the volume i have] and tried to pour it into my lube-sizer from Lyman...very slimy and didn't harden up to even be usable so i have a mess to boil out of the sizer.
i had a second batch of the same and added the same amount of peanut oil and it seemed to set up a bit better so i pan lubed some 520 gr boolits and froze em to help the sett-up. still a bit snotty but hung in the grooves till i got em loaded...got a nice lube ring on the muzzle so i guess it is working good but man that snotty texture is crazy.
maybe i got too much oil in the mix huh...or is SPG a bit snotty too? never used the original stuff to be able to compare..........
