Hello, Maxim. I have the Lyman 457122..The so-called 'Gould" hollow pt. weighs around 290gr. No real problem with hollow pt. pin..usually need to run pot a bit hotter..and if interuptions..simply dip pin into alloy for a few seconds to bring back up to temp. Never had an issue with top-punches..I assume you are concerned with collapsing hollow? No neeed to worry about that. I have been using flat-faced punches anyway to aleviate any punch/die runout. Best of luck!
