Re: home made case lube
When time is of no consequence AND you're rocking a single stage press...OR you're doing heavy forming of cases, imperial sizing wax is the slickest stuff I've ever come across.
The 99% alcohol and lanolin also makes good lube, but I've found it isn't easy to get off, particularly if you clean with stainless. If you're only putting 50-100 cases in the tumbler, it comes off fine, but if you try and run a big batch, there just isn't enough water/detergent in the tumbler drum to emulsify all the lanolin. You end up with 1/3 to 1/2 of the lanolin emulsified in the water/detergent, and the other 1/2 - 2/3 in a homogeneous oily coating over everything inside the tumbler.
I load en-masse on a progressive. I will deprime and resize hundreds of cases at a time on the press, then clean with stainless, then put them back through the press to load.
I've found that for basic FLS'ing or NS'ing, plain Ivory liquid dish detergent works great, and obviously comes off in the tumbler just great. The trick is to not use too much Ivory, and to allow it to sit for 15 minutes to "dry" into a waxy coating on the cases before sizing. Otherwise its lubricity is shit.
If you go the lanolin route:
You'll need "100% pure liquid lanolin". Cheapest place I've found it is on Amazon.com.
The 4oz bottle will make a gallon (or close to it) of lube. Trust me, a little of this goes a long frickin way.
My local walmart/meijer carries the 99% isopropyl alcohol.
ONLY use 99% alcohol, as a lower percentage will not dissolve the lanolin properly.
