lubricating brass

Actually, I would argue that they're ALL cosmetic.;)

Unless they're severe enough that the case won't chamber. At which point they become functional defects.

I have fired a great number of dented cases. 60,000 psi has a way of smoothing them right out.:p

It only takes a few thousand psi to make that dent go away. It has no effect on final pressure or safety.
 
I also don't agree with it being cosmetic, the lube is defoming the shoulder.

Ok, the shoulder has a small dent in it. And then what??

If the case body gets deformed, then it has the strong potential to pull the alignment between the case and the mouth of the case out enough to make a difference in accuracy.

Well, I try to resize my cases to all be exact. A little dent here & there to me isn't exact, but that's just me. Does it matter, may and may not. If all my rounds are exact & one goes south, just one less thing I can blame it on. I'm only reloading for benchrest shooting, try to remove every minor issue in rifle or round. Just wsh I had 20/20 vision, my biggest excuse.
 
I would not want a dented round if I was shooting for maximum accuracy. I doubt it would have any dicernible effect but why risk it? For normal hunting rounds it wouldn't bother me though. If my loading technique was consistently producing dents, that'd need to be fixed. Just one, no biggie.
 
"Hydraulic dents" from lube can be "shot out" as many other irregularities in brass. If the dents are rounded, do not have creases or sharp corners, the dents can be shot out (or inf one is really inventive, fill the case with water and "hydralically" push the dent out like one would deprime Berdan cases. I recently read an old article on "fire forming" that was done with a die and a ram; cases filled with water, ram inserted and hit with a mallet. Hydraulic pressure "fire forms" the case into a F/L die). Ever pull a dent out of a fender with a suction cup? As long as there are no sharp corners, the dent pops right out...:D

Got a source for 100% Isopropanol? The 91% is pretty common and 99% typically takes a chemical or pharmaceutical supply house, I have never seen 100% Isopropanol Alcohol.

I bought 99% at Fry's electroNics for cleaning flux off of circuitry. I never tried it to make my own case lube but I can assure you that Dillon case lube (lanolin+alcohol) is not 99% and it works well.

Been there and done that, about 40 years worth. :) Those trons put beanies and weenies on the table.

Lol. I just did it as a hobby. I bought, repaired, and sold 60's/70's silver-face stereo equipment. 15 years ago thrift stores were chalk full of the stuff and then the 'hipsters' arrived and now you can't find that stuff for cheap anymore unless you luck-out at a garage/estate sale.

Yeah, started as a hobby as a kid with an ameture radio license as a kid in '63. It evolved into a career. Still have piles of test measurement and diagnostic equipment piled up around here from my work years. Really need to clean that stuff up to make more gun room. :)

I was going to rig my .308 Remington 700 with a sensor and try and look at pressure curves but have yet to get to it.

Highly recommend Imperial sizing wax. Just a tiny smear lubes even the most stubborn nato bottleneck cases. A small tin lasts a LONG time as well. I resized -06 cases to 8mm mauser with little fuss using ISW.
