.223 and 300 blackout cases getting stuck in my dies

[Caveman Jim]

1 part Lanolin oil to 10 parts "Heet". I use rubbing alcohol greater than 70% alcohol.

Mix in a spray bottle that I got in the "travel" section of your local store (where they sell the travel sized stuff - toothpaste, deo, etc). Spray bottle was ~ $0.97 I think.

Then i wandered over to the isle that sells the rubbing alcohol. Get greater than 70% alcohol content. 99% would be ideal, but >70% works too.

Lanolin..... that's a different story. I ordered off of Amazon. I think any feed store might sell is as it is used by farmers on their cow/goat udders (to keep them soft and supple).

Mix in spray bottle 10:1. Shake. I lay a bunch of shells on an old cookie sheet. A quick spritz to get the top-side "wet". Then shake to get it all over the cases. You could also do the zip-lok bag spray and shake too.

Let the alcohol air evap for about 2 minutes then started running them through the sizer/decapper.

I haven't had a stuck case since.

Lots of YouTube videos of people using HEET (the automotive fuel line conditioner sold in auto parts stores). I found the rubbing alcohol to be cheaper and it works the same principal (to act as an agent to thin the lanolin so it can be used in a spray bottle, then evaporate quickly leaving a thin coating of lanolin).

I get the Heet at the dollar store for…

Hmm I use whites sewing machine oil and a felt pad. It has been a long time since I stuck off a case. But I use a single stage to size all rifle brass.

Tested this last night. I have 49 rounds of 30-06 military brass that was not fully resizing in my RCBS die. After cleaning the die with a gun cleaning brush it went further but would still not full insert even applying Hornady one-shot liberally. After reading this thread, I grabbed the Lee case lube and tested it. It went straight in and fully resized.

I imagine the OP brass is actually 5.56 military brass? The 300 blk was probably made from 5.56.
