I have a ton of once-fired LC brass in which I have to remove the crimp. Well, apparently with the RCBS FL die set the expander ball started to unthread during a heavy session (I've got THOUSANDS of this brass)––sure enough I broke it 
RCBS gladly sent out two stems and advised me that a dab of blue loc-tite will help. Also considering using a univ. decap die just for these OFB with crimp. First time I've ever busted a stem

Quoted:
The blue loc-tite is "breakable" compared to the red as far as breaking it loose  Tell us how well that works out for you when you try to use pliers or a vice grip to squeeze that soft expander in the knurled area while rotating the stem to remove it. 
Even with blue loc-tite, make sure to only use alittle and then maybe heat it if you need to remove it. I love RCBS stuff but the stems are the weak point in their design. Their customer service makes up for the flaw though. |

Heat helps.
One other thing I picked up from Colt for preventing threads from walking. Put locktite on just the threads and and let it dry, then thread it in. I saw they did that on my first AR, the front pivot and screw pair had that loctite treatment with red loctite. All it did was give a bit of tension while unscrewing, enough that it wouldn't do it on it's own. I find more trouble with Redding undersized pins dropping out of the collet jaws on the stem. Not much worse than going through 300 pieces of brass in a box looking for your pin. |
