~25mL STP oil treatment (contains Teflon)
1 regular tub of Vaseline (13oz/368g tub)
5 crayons of the same colour (just to colour it)
~1L of candle wax
The usual method of standing the bullets in a silicone baking pan. Pour molten mix to just above top grease groove. Let cool overnight (maybe less since it's not summer anymore; still my first year doing it). Flip pan, pull out hardened sheet (quite a bit softer than pure candle wax but still hardish), push out bullets from behind with my fingers.
When at ~20'C the mixture is firm but will flex and take a finger indent quite easily. Not as soft as a lot of the black powder lube I see (which is designed to be able to be applied with fingers) but softer than candle wax.
I use it for my 500gr .45-70 bullets and find they shoot as clean as jacketed projectiles up to ~1450fps (as fast as I have pushed them.)
