I don't remember who it was on here that posted that a fellow could send RCBS a sample of three boolits, and they would custom make you a seating stem. Well whomever it was THANK YOU SIR! I was having problems with my .40 cal seating and the boolit getting cocked to one side ever so slightly and shaving a smidgen of lead (or powder coat). I know most wouldn't bother but it rankled me to no end..... I contacted rcbs, got the shipping info, and off it went. It took about a month but I got my seating stem back today. My sample boolit was a NOE 175 gr round nose. I just got in from loading about 100, and not a single one had a shaved side. I'm tickled pink! :happy dance:

Nothing beats fine tuning your reloading process. What did they charge to make the stem?

Looks like it was $28.61 all done.... which is reasonable to me for getting perfectly seated boolits. Those small bits of shaved lead on the case mouth really sent me up the wall...

I filled all my seating stem pockets with a hard epoxy. Never looked back.

For almost free you can use JB weld & make your own custom seating plugs. Works great for LHP.

I thought about epoxy, and the like after the tin foil trick didn't work too well... Then I could envision seizing my plug in my seating die.... and replacements are too expensive, and hard to find!! :(

Good information for the masses.

I've always used hot melt glue - never mars, quick to do and lasts a long time.

To prevent seizing the plug in a seating die, use a mold release. I have used J&J paste wax as a mold release to customize seating stems so they do not mar the bullets. You will want to use a quick curing epoxy that remains somewhat flexible on curing.
