I don't understand the complaints about the price of Imperial.
I paid about $5 for the 2 oz tin, in 2008. I've sized about 6k cases with that tin.
have to buy another tin in about 15-20 years, when there's still 3/16 oz left, but it's all in the corners.
So, it's costing me about.... $0.20 to $0.25 per year
You don't need much. A little goes a LONG
way. Quite often, when I'm sizing large batches of brass, I won't even lube every 2nd or 3rd case. The little bit of residue in the die is enough.
No wrinkled shell shoulders or excessive amounts of resizing wax seen built up over time on my dies de-capping stems.
Excess lube is excess lube. It doesn't matter if it's wax, 'goo', glycerin, oil, petrolatum, or an aerosolized lanolin-alcohol solution -- too much is too much; and they all show it in their own ways.
