Hey everyone, I've been looking for a universal deprimer for 300WSM cases and I'm pretty sure the Lee is too small, advertised for cases with up to .550 case diameter, the 300WSM has a case diameter of .540 just before the shoulder but .555 at its base, so my question is would the Lee universal deprimer work, or is there another deprimer that I should be looking at?

I've been using one of these bad boys lately...

http://www.harveydeprimer.com/

Works on everything from .223 Rem to .338LM so far. I had to get a special decapping rod to work with the stuff that uses PPC sized flash holes (6 BR/Dasher, .308 Lapua Palma, etc.) but other than that, it is way over engineered, solid as a rock, probably last several lifetimes.

I just tip it over and dump the spent primers into an old Cool-Whip container for later disposal in the trash. Works great.

That is damn impressive... but not what I was looking for haha. All I want is a deprimer die, I'm just about to get the redding die but I would like to know if the lee definitely works or not before getting it, I ordered all Lee equipment (as you can tell, I'm a beginner) and would like a Lee depriming die to go with it.

Rusty,

I have a Lee universal decapping die and it will work with my 300 wsm cases. The opening in the bottom of the die measures 0.565. Hope this helps.

Kind regards,
Jared
