BTW, none of those issues manifest themselves with a pistol (straight walled case) and pistol dies are for the most part all carbide inserted, which also eliminates the case lube regimen too. Pistol cases are sized and loaded/crimped dry. I infrequently shoot a quick spray of one-shot in my sizer die for ***** and grins if nothing else.
Been loading NP cases for a good long while now. NP eliminates the tarnish from handling issues.
I have some NP 308 cases and I'll keep a close eye on them. No issue trimming with a WFT. I run a solid micrograin tungsten carbide end mill in my trimmer.
