Lube for expanding using pin

[savageshooter86]

What lube are you using for expanding necks with as final step after resizing cases with pin gages ?

Just got a Porters precision die and pins.

Since there can be many ways to organize your brass prep, this is another it depends answer. However, when starting out rookies, I suggest they use the same case lube they use to size the body, and then make sure their cleaning method removes all of it.

I FL size first. Then expand as last step. I currently use imperial sizing wax for FL resizing

I treat/clean mandrels/pins with Hornady one shot. New/clean brass dry graphite inside the necks, applied with neck brush. (I'm a hunter).

NeoLube before I expand, NeoLube before seating the bullet. Yes, I use a Porter Precision Product pin sizing die.

I'm liking NeoLube #2 these days.

I use sizing wax, works great.

Once I have a layer of carbon on the inside of the neck (not new brass), I don't need to use a lube before using an expander mandrel.

I dip necks in powdered graphite coated ceramic beads prior to expanding, then wipe any powder off the neck. Brass goes straight to load blocks for charging/seating.

Neo lube, I expand and go directly sizing

When I use carbide pins, no lube is ever needed. Short Action Customs makes them in .0005 increments. No galling and they work perfectly.

Expander Mandrels

Achieve consistent neck tension with durable Expander Mandrels. Precision tools for reliable reloading results.

Everything from SAC is great, but their website says their mandrels only work with their own dies, but that is incorrect. I use mine in a Porter precision dies, since I already owned a few.

David thanks for the info. I’ll look into them

For now I tired hornady one shot and helped them expand super smooth. So we will see what my test at 1000 yards tells me about the different size pins

Imperial
I also use it when pressing in gears and bearings, so it works good for other things besides sizing cases

 

[Pappy1959]

Hornady One Shot works great but I make my own case lube using the Lanolin and 99% alcohol mixture. Its a 10/1 mixture.

This. I use a carbide mandrel also.

I use Sinclair dry lube in my new Lapua cases before seating the bullet. I found this gets my velocity's closer to fire formed brass.

Technically, a SAC expander mandrel will work in the Porter but, not in the way SAC intends their mandrel to operate. Any expander mandrel (pin gage, SAC etc.) used in a Porter works on the downstroke; it expands the neck from the mouth to the shoulder. When a SAC expander mandrel is used in a SAC modular die, the expander operates on the upstroke from the shoulder towards the mouth. I don't want to put words in SAC's mouth but their reason for the design is to eliminate expanding an unsupported neck, whether that makes much difference or not is a matter of opinion I suppose .

I used to use Neo lube 2, when I was running the porters Precision in 300 Win mag.

Good explanation - so, essentially, the SAC expander mandrel functions like an expander ball in a conventional die but is technically more sophisticated.
