Lubrication is absolute essential in the reloading process, Here are a few ideas on which and how. READ MORE
What’s the most important thing in case resizing? Case lube! Overlook it or under-do it once and you’ll know why! A stuck-case remover is one of my very least favorite tools…
I have long used and recommended petroleum-based case lubes. More: I prefer those that are applied by hand, literally with the fingers, because I think it’s a better assurance that the right amount, to all the right places, will get laid down. I will quickly concede, though, that they are messy and slower than other methods.
Spray-on-type lubes are very often used and recommended, especially by high-volume loaders because a good many cases can be treated and then even stored before use, so say the claims. I strongly suggest taking steps to prevent the lube from finding its way inside the case. A thin piece of cardboard placed atop the standing cases works well for this. There’s worry otherwise that the lube might affect the propellant. That does depend on the formulation, but I prefer the “no-chance” approach. I’m a “slow-down” sort of loader. That doesn’t mean I don’t want to save time or be as efficient as I can be, but I’ve just not found the speed advantage to spray-ons to overcome their performance. Sprays are not quite as “slick” as rub-ons.
Lanolin-based and wax-based alternatives also have their following. As do water-based lubes. The wax lubes indeed work and also clean up (off) easily, as does lanolin. I’ve not been a follower, though, because I find many to be more difficult to apply evenly and, one more time, just not quite as slick at petro-based products. Some of the wax-based lubes also make claim to “apply-now, use later.” I’m not sure what the appeal of that is, but there it is for those it appeals to. There are also a number of “proprietary” formulations out there now. I have not tried them all.
A tip I picked up umpteen years ago by the man who got me started loading was to get an ink stamp pad (office-supply store variety) to apply roll-on type lubes. Indeed, that works way better than the industry pads I’ve tried.
Back to petroleum lubes: aside from providing smoother feel in sizing, which I have to believe also indicates “better” lubrication qualities, these don’t build up as much within tooling. I take apart my sizing die every now and again and swab it out, like I would a rifle chamber.
For best results, no matter which lube type you’re using, an even (thin) coating gives best results. With a good petro lube, it doesn’t take much. If you see any denting (usually in the case shoulder area), that resulted from hydraulic pressure and is a sign there was too much lube (too thick a coat). No worries, though: shoot the case and they’ll iron back out. Just use less lube next time!
Lubing the case neck inside is debated, but I favor it. However! Only very sparingly! That is why I really like the finger-applied lubes: just a little “wipe” across the case mouth eliminates the “gaunch” noice from the expander. I don’t use the graphite-applicators (the bin-and-brush types) because I haven’t noticed a whopping lot of difference in neck sizing with or without it.
And, by the way, lube a case each pass through the die. This is important when setting up a sizing die where you might make a few passes with the same case. Don’t risk it! Stuck cases are total mood killer.
Clean the lube off the cases! There will be some now who will just roll their eyes, but I use denatured alcohol and a bath towel pour some on the towel, but the cases on the towel, fold the towel over the cases, and roll them around. Fast and simple! That works for petro-based. Others need more attention: just rub it away, or use detergent.
I do not recommend using a tumbler-type cleaner on loaded ammo!
Sho, there is a (slight) chance that a bullet tip might detonate a primer, but that’s not why. Why is because the propellant gets pulverized, and that, no doubt, will change its burn characteristic.
The reason to clean off the lube is because it lubricates, and that’s a bad thing on a live round. The case is supposed to stick tightly to the chamber when it expands under pressure. Any slip increases bolt thrust. I once saw a fellow douse a loaded 30-round magazineright down the middle with WD-40, to “make sure the bullets fed…” NO NO NO. Oil on a cartridge doubles bolt thrust!
Case lube is not a case cleaner!
Make sure the cases are clean prior to sizing. They don’t have to gleam, just be free from dirt and gritty dust. If you’re seeing a applicator pad, for instance, getting a dirty spot on it, well there’s your clue.
We’ll talk about that next time.
