RCBS case lube was STP and it was water soluble if I remember right. Haven't used it for years. Use Bag Balm now, much cheaper and one box will last the rest of my life.
Not STP. STP is anything but water-soluble. I long thought it was some form of lanolin, but it's not that, either. Some long and unspellable chemical name that I forget.
a lot of CANADIANS & BRITS, use UDERLY SMOOTH, hand cream. they put a dab on the bullet / lead head before inserting it into the chamber. we call it UDDER BUDDER. the BRITISH shooters forum in CANADA shoots, that they have use it. you can get a tube or can of it at any prescription center.
The early JDJ cases by SSK were all contender based cats and used the 225 Win Mag case to get 65k pressure rated rimmed cases.
Today according to the owner, Star Line only makes 65k proofed 30-30 brass.
You just need to use new unfired Star Line brass to step size and form. Use a 7-08 die, a 6.8 SPC die, then the 6.5 die with a 30-30 shell holder, fire form, one shot and only one shot, a full house, standard load. Please lube in and out of the neck with "case lube."
I have had several of the neck up or neck down single shot cartridge guns for the handguns made by BF, XL, Merrill, TC, MOA, etc.
STP - (Scientifically Treated Petroleum) is a petroleum based lubricating oil with a long chain zinc based additive included. RCBS case lube is, and has always been, lanolin based. Lanolin is derived from the natural oils present on sheep wool. They are two completely separate things.
The STP has worked for me-same bottle for 15 years, still almost full. I use it primarily with Hornady 300BLK dies and Nickel plated brass, and with 308 being necked down to 7mm-08.
I had problems with the Hornady 300BLK dies and stuck cases. I switched to a LEE sizing die and the problems stopped. So, I am back to using Hornady One Shot as my case lube, for 300BLK.
The STP inside the neck really helps get through the doughnut restriction on the up stroke after necking down.
I totally disagree with your position here, sir.
By annealing you make the brass soft enough to conform to the new dimensions.
Not annealing will sometimes stress the brass such that the case collapses or the necks split.
Been there, done that, have the shirt.

Maybe they have changed the name but originally STP stood for Studebaker Top Petroleum. Can be easily removed with carb or brake cleaner.
I use one of those flip open cases that calipers come in with a piece of sheet foam in the bottom saturated with STP and Q-tip.
Roll the case over the foam,give the inside of the neck a swab and size and give the case a squirt with brake cleaner and blow it out with compressed air.
When I made 6.5 Remington Mag from 7 Remington Mag I found out that new cases had worked better than once fired. I had no reject’s with the new cases. I annealed after they were formed and trimmed.
