I have ruined numerous sizers from dirty or grit-embedded cases.
Yet to ruin a sizing die from sizing any kind of cases, even when using hardened steel dies used for rifle calibers, this is in 50+ years of reloading. However I do rinse my cases before sizing.
I rinse and let dry
Tumble to polish
Mayhap I'm just 1 lucky little pup!
