Warpig was specific about rifle cases and a .30 carbine is a rifle. And before one starts the argument about .30 carbine "MAYBE" being a pistol case. I've shot Remington fireball and Thompson Contender in .308 and 45-70. They're rifle too. Reloading manuals put things all over in their books.
His advise on not bothering with too much case prep for pistol is sound. Use them until they crack and salvage them out. You'll probably lose them before that even happens...
