and at different temps.
we have to concentrate on the outer edges of the lube, the middle will take care of itself. I sure agree with that based on experience.
even if we come up with the correct numbers as far as the stresses the lube will see, it most likely be defined at 70f. Or 210 or 104 and so on. Tough nut to crack anyway, since no one has a clue what the temperature of the lube film is between boolit and barrel just before muzzle exit.
we still have temp swings and bore condition to consider. IOW carnauba sucks!
this is where the extraneous [wow big word there] oils will come into play whether they be synthetic or natural,or a refined of either.
the base being consistent over temp swings is still going to be the big hurdle.
