RPA 6mm BR

Thanks very much for the excellent explanation, that helps a lot.

What temp tempilaq are you using for timings as although the case is out of the flame it sits in the next station for a while and surely the annealing process continues for a short time? Would it not be better to have the torch annealing the case before the discharge station rather than the one before that? I just wondered if you were allowing for this by using 700 degree rather than 750 degree tempilaq? Are you using the tempilaq on the inside of the case mouth?
