    Synthetic Motor Oil for Case Lube?

    I was watching a Youtube presentation on preparing .223 cases. The guy used Mobil 1 for a case lube. Has anyone here tried that? How does it work and are there any downsides to using motor oil? I appreciate any input.

    It would'nt be my 1st choise. I personally use case lube for lubing my cases. I guess it would work in a pinch, then again so would a can of cheap lard.

    Apparently he's not the only person using synthetic motor oil. A little goes a long way - a quart of Mobil 1 would probably last the non-commercial reloader about 5 lifetimes!

    Concerns? I'd just avoid using a heavy weight oil, which should minimize the likelihood of hydraulic denting. Getting the lube off once the sizing operation is done is important, and I'm not sure that tumbling media would do a good job of removing traces of oil.

    The commercially-available case lubes from Lyman, Dillon, RCBS and Hornady are commonly made from animal fats and are at least alcohol-soluble. RCBS' 'Case Slick' is water-soluble, which would make removal easier.

    Not sure it would work the way I lube cases,my concern would be getting lube inside the case and compromising my powder charge getting a pop instead of a bang

    Guess I would make sure I changed the oil every 3,000 rounds....

    NO!.... ONLY used lubes that will wash off with water or dry on there own...... you CAN use glyercen, this is the mane base for RCBS lube for the pad, but my new fav is the RCBS spray...

    drop a few hand fulls of brass in a Tupperware bowl, 2 sprays, shake, 2 more and done....

    I used the old STP for years with no problems. A quick wipe with a solvent dampened rag took it right off after loading/

    If you are not extremly careful, a small amount can contaminate the powder.

    Not to mention more risk to contaminated primers as well.

    I'd not be interested in lubing cases this way. I like the water-based case lubes myself.

    Well, I tried it on 10 30-06 rounds. I cleaned them for 30 min in the tumbler after sizing. I am going to let them sit for a few days then take them to the range. I will post the results here.

    They make case lube a certain way for a reason. Hornady makes a spray on lube that is quick, and doesnt contaminate primers or powder. If any oil is in the case, the tumble media may stick to it and not come out. It seems backwards to me to lube, decap and size, and then tumble. The whole purpose of the tumble is to clean cases before running them thru the dies to prevent undue friction and wear on the dies.

    The things I don't get about the spray on lubes are:

    1. How do you ensure that you get the lube in the case mouth?

    2. How do you keep the lube off the case shoulder?

    3. Do you not have to wipe them off the case or otherwise clean the cases after resizing/decapping?

    They do sound less messy than other methods and lubes.

    2. How do you keep the lube off the case shoulder? Lube on a case shoulder is not a bad thing, to much lube on a case shoulder is. It doesn't take much spray to lube a case, in fact its hard to get enough spray on a case to have shoulder dents. As for the lube pad a couple drops of lube spread out then worked in with your fingers before rolling cases is all that's needed.

    3. Do you not have to wipe them off the case or otherwise clean the cases after resizing/decapping? No not really. I know guys that shoot sticky cases all the time. Its kinda messy but everything cleans up with soap, water, solvent or oil depending on what you are cleaning. I personally tumble my cases after resizing.

    I've only reloaded 223 so far on my dillon,and using Dillon spray case lube I have never had any cases get stuck,and I've reloaded thousands of rounds,I found that lee dies do not resize the cases for AR15 chambers,changed to RCBS small base dies and every round feeds flawlessly

    I use a universal decapping die. I decap, tumble, lube (Dillion works a lot better then Iosso), then resize/ load. In this order I can just grab a case and go on my Lee Turret.
