Kicking a dead horse here 100% but I kinda wanted to revisit this and get in my two cents.
Is Sharpsmans method a viable method? Absolutely. Brass is either annealed or it isn't. As long as the web isn't over heated and the shoulders/neck hit temp you're good to go.
But why in the F#$% would you wanna tighten a HOT collet on every piece of brass vs. using a socket and a pair of pliers?
Yet the guy who spends $500+ dollars is the idiot? LOL
But he's been doing it over 60 years and knows what's best...
LOL
Pop the casing out of the shell holder and pop a new one in...I don't see how it could be much easier? Maybe 3 seconds?
