Cure for loose neck expander plugs.

[Motor]

There was a thread a few weeks ago on this and I couldn't find it but since I had both my "M" die and my RCBS neck expander's apart today and found both were not tight I searched for a nice easy cure.

I found it in my plumbing tool box. PTFE Thread seal tape. (white Teflon tape) Only one wrap does the job nicely. :)

Good to know as I just had to REresize a bunch of 223 as I didn't notice the expander plug came off till the end of the batch. :(

Just a touch of "Blue" Locktight will keep them in place. Removal will require the use of tools. Iron Whittler:Fire::swagemine::castmine:

I use a small O-ring between the plug and die.
