In bottle neck cartridges, full length sizing, how do you lube inside necks? Do you?

I was using a brush rolled on thelube pad, but that seemed too slow. It probably wasn't that slow. I tried lyman spray lube, but it didn't do much for the necks, and I ended up with splits.

Now I'm just scraping the neck accross the lube pad, picking up a little lube. I do this every 4th case, and I'm not getting splits or much lengthening.

Does anyone use mica?

I use this:

It is slow but the split necks will stop and it does make seating the bullets easy.

I've tried a lot of ways, from a q-tip with a bit of stp, to those thing's with brushes that you dip into somekind of white powder and now I use Hornady One Shot case lube. The best was stp but slow and you had to be careful not to use to much. That stp really reduced neck streaching. Now I just spray on Hornady One Shot. Spray down onto the neck and spray a little in the die, work's great.

do you have to clean the necks first before the lyman case dipper?

Most of the time I just use the Hornady One Shot as described above. When needed I use Motor mica by Adding a tsp to a couple ounces of #9 shot in a Speer or Burger empty bullet box. The shot carries the mica up into the inside of the neck and knocks out any extra. works like a charm. I do this when I'm neck sizing and don't want to have to tumble the cases to clean them. I work hard to reduce the run-out on the case necks and feel tumbleing is another chance for missalignment. I tumble them clean before I start but don't want to after sizing, other than full length sizing.

I have a few techniques....for full length sizing 'large rifle' cases, I use a foam pad to lightly lube my brass. One corner of the pad I have a 'wet' spot....more lube than the rest of the pad, just push the neck straight down into the wet spot. You really don't need a lot once you start going and the expander ball is lubed...maybe a little more at first. 2. For small rifle and cases that pass through a little easier...I roll the bass very lightly so that only the main body gets lubed, then I dip the neck in Imperial Dry Neck Lube, (graphite) ...works wonderful...just tap the case when done sizing and you don't have to worry about cleaning wet lube out of the neck, or contaminating primers and powder. On the downside...the necks get black, and so will your fingers. 3. When I can...Neck Size Only...with just the graphite. I have tried adjusting Full-Length dies so they just neck-size...but it dosent work well with all cartridges. I wish I had bought neck-size dies all the way back in the beginning when I first started buying dies. For my 35 Whelen Imp, I bought the Redding 3 die set with full-length and Neck-size dies. I have only used the full length die once....I just dip in the Imperial (graphite) , size the neck and they are done..The necks get black....but NO CHANCE Ever or fouling primers or powder. Of course these cartridges should ONLY be used in the rifle that fired them.
4. Pistola....or straight walled cases....also graphite only. Some dies say they do not require lube for pistol cases, but I use a little Imperial anyway. I just wish they could come out with neutral colored graphite.

For neck sizing I only use Mica, just dip the case mouth in it. For full length sizing I use Imperial Sizing Wax by Redding, just wipe a little on the end of the case.

A q-tip w/ that white lube in a tube from lee, beats motor mica by a bit, and does not need to be "cleaned" and won't degrade powder... Marty

You could always just order a carbide expander ball for your resizing die if you use RCBS or Hornady. I have them on some of my old dies, they work but I cant remember which dies have them anymore so I lube the necks anyway. I lube the necks of 5 or 6 rounds and sit them aside than run them through the die every third case. I really dont need to lube all my cases necks and throats Im resizing. Every third case seems to lube the dies neck and expander ball areas just fine.

I use the Imperial dry neck lube - ultra fine graphite in a Bonanza case neck dipper similar to the Lyman shown in an earlier post. I like the graphite better than the mica offered by midway. But its a little dirtier. Cleans off the outside with a wipe of paper towel. I don't like the Midway case neck dipper as much as my Bonanza either - too big a reservoior and the top doesn't stay on well. I think Redding is offering the imperial neck lube these days. It sure reduces neck stretch on my cases.
