So just recently started using a mandrel to resize case necks. I universal decap, resize without expander then use a Sinclair mandrel die with a .262 mandrel to give me consistent neck tension. My issue is how does everyone keep the mandrel from coming out of the die? I've taken to dipping the case into my sizing wax but seems like at least 3 out of 50 I pull the mandrel out with the case. Also it's hard to shove them up onto the mandrel any advice would be appreciated.

Not saying this is right but here ya go.
Depending on how you tumble or clean chamfer the inside and outside of the case.
First I use 1 shot in a bag. And I try to get it everywhere so I don't have to lube neck insides.
I have also moved to using 2 mandrels for the most part. I now size most on my 650...
So after chamfer and lube
Deprime
Undersized mandrel
Case size
Correct size mandrel

I have the same mandrel die, so something doesnt sound right. When case is pressed onto the mandrel, there is not much resistance. And even less when the case is removed. When the die is assembled, you take off the cap, insert the mandrel into the die ands then replace the cap. The shoulder is pretty beefy, so there is no way you could pull it out of the die.
I too am confused at how it’s pulling the mandrel out of die body.
I do mt deprime , size and mandrel then the cases get chucked into a wet tumbler with lemishine and dawn then tossed in the over for about 20 minutes

I've ordered quite a few Sinclair items that were out of stock and most ship within a week or two. Another option is the 21st century die body which is the ones I personally run.This is what you need. Unfortunately out of stock.

From my research yes but I’m also running the 21st black nitride mandrels so haven’t checked myself.
I dry tumble with walnut media and I do not lube the necks, haven’t stuck one yet.
Yeah, the Sinclair, 21st cen and pma mandrels and bodies all interchange with one another.
