How Long Can You

[WFO2]

How long can you leave LS 50/50 in your lubesizer . It may be months before I cast again and need to use it .

I had a few boxes Javelina that was at least 25 years old; it seemed no different than LARs version in terms of feel and smell. No issues with performance in 30 M1 Carb handgun & 44 mag. This was stored in the white cardboard boxes.

Basically, the lube is in a container sealed at both ends. I would be more concerned about leaving the lube sizer just sitting and collecting dust. Keep it clean and in stable temps and it will be fine. You might want to wipe down the ram with a damp oiled cloth to clean off the dust and refresh the lube before next use. It would be helpful to back off the pressure nut to prevent pressure causing lube to leak.

good advice there.
the cool thing about bees-wax is it can be rejuvenated by re-melting it again.
leaving it in a sizer for a year and re-pressurizing it won't have any affect or show any difference than the last time you used it.
10 years, yeah it'll get hard.
melt it again and it's good to go again.

Sounds good I did back off the pressure nut . Since it will be kept downstairs in my reloading room I'm good to go .

I got 2 lubrisizers for cheap last year.Both dusty and dirty,both had some kind of lube in them.I shot it like nothing happened,just changed sizing die and that was HARD.

When working with very old dried up lube, you may consider warming the press well to soften the lube. Do not overheat and damage the O rings though.

GONRA's pure Alox 2138F sat in my Lyman 450 Lube Sizer for decades.
Normal room temperature, low humidity. Nothing Bad Happened.
