PC or lube, which to shoot first

I have come into a quantity of each, 200g RNFP up to and including 250 Keith SWC. I'll be loading and testing in with a 44 special and 44 mag hand guns.

My question(s) is do you shoot one before the other? Do you clean after one or the other?

Prior experience is with commercially acquired cast only. I neither cast nor powder coat.

I'd shoot PC last. It may help clean the barrel. I see no reason to clean in between the two types unless leading is present.

Thanks Dinny.
