You can but a 2 lb tube of of for less then the cost of a tin of imperial sizing wax and its the same thing. Lanolin is also the main ingreditiant in lee and dillon lubes. I also use it to make cast bullet lube. A tub of it will last the average handloader two lifetimes. Ive found NOTHING better for case sizing.
Great tip, thanks!!!

You have a quite impressive reloading shop!

Re: 8mm brass 7mm stw

I haven't found any 8mm brass to neck down either. I read in one of the precision shooting books a guy was necking down 300 h&h brass and fireforming. He actually gained a couple of grains of capacity. I don't know how Norma made the Jarret brass but that may have been what they started with.
I did find some remingtion stw brass at cabellas yesterday. I don't know when remington is going to make another run. I called Nosler last week and they said they were expecting a March run and brass should be available in early April.

This threads old now but let me try to get a little more info if anyone still hanging around on this thread.
I just got a 7 STW, and 40 rounds from the builder, problem is the ammo was destroyed in shipping. He's sending more but 40 rounds won't last long. I bought some 8mm mag brass to neck down. I've tried a couple with Rcbs FL die. It necked down well, and concentric, no expander ball. It leaves a donut at the neck shoulder junction. Should I fire form with reduced loads, or can I shoot these cases at full power with good results. The load development is already done, and have load data.
I've heard both here, and still not sure what my best option would be.
I'd appreciate some more direction.

Well, I'll beat this (dead) horse again.
The case on the 7stw is fully formed when you run a 8rem through the sizing die, so no fireforming is really necessary. If you have an extremely sloppy chamber you could fireform but it is a firing off the case for little gain. If you are running the h@h casings through your 7stw die for casings I would fireform as your capacity will be quite a bit less as the case isn't fully formed.
