It is not required to lubricate cases when using a carbide sizer die.
But, it doesn't hurt, either. I use Hornady Unique and lightly lubricate every fourth or fifth case. The carbide sizer has some porosity so the lubricant will still be effective for subsequent cases. There's no recipe; I go on "feel". If things are going smoothly every fourth case, I will go to every fifth. If they start to drag after the third, then it's every fourth.
I don't load for the 454 Casull, but since it is a pistol cartridge that crosses the line into using small rifle powders, not pistol powders, in that arena, I have always had my best luck with 2400, H-110 and to a lesser extent IMR-4227.
