Nice work. No variation when checking after?

Bought a Forster 3 brush motor mica lubricator years ago. Never liked the mica except for not making your hands black. Didn't use their 3 brush holder long before I just unscrewed the brushes and used them individually.

Still experimenting with different inside neck lubes since I converted to expander mandrels and stopping using bushing dies.
Used the wee balls (or shot) and graphile method, Imperial Wax on a cotton bud, One Shot sprayed at an angle into the neck and so on.

Wanted to try Neolube but couldn't get it. Brewed up what I believe Neolube is but wasn't that successful, the IPA evaporated to quick. The Neolube or my equivalent is applied to the to be seated projectiles. AMP has done a decent amount of research on this.

@johnd I'll make an applicator like yours. Nice one. Simplest is best. Should be posted in the homemade reloading tools section.

@zimmer thanks, yes I have done the home brew neolube, i used Bunnings isopropyl that stays wet for a bit longer before flash off, but i think that the liquid was running the lube off into the tray. It did provide a small level of lubricity, but maybe not enough.
I think the tension has gotten mixed up as i combined two brass lots, but most of this brass is well up on firings..... maybe 10 and 15.
@charliehorse they have sprung back to about 0.3065 - 0.3060 from what I can tell (vernies in the neck) Still the odd one that feels tight when passed over the makeshift mandrel, but i cant determine a definitive measurement. When I seat a proper bullet in them i can cull the heavier seaters out.
Probably 95% have been cured, but the proof will be in the elevation spread. I've either recovered some grouping or lost it completely

I used the Jaycar IPA which is 99%. That may have been my problem with it flashing off too quick. Bought it during the Covid crisis.
The Bunnings (and the M10) versions I think have a water content.
I originall tried it after learning that RK used that method. Don't know if he still does.
