Or anyone else who might know!
I have a NOE mold for 44 mag/444 that is a copy of the Ranchdog molds that work so well in Marlin rifles. It drops right at .432. I have been hand lubing them. Tired of that process! A .430-431 can be polished out I'm sure. But have no idea what top punch would fit. Any ideas?

User “ammohead” will make you a custom H&I or Star resizing die with the proper punch insert.

Why not use a flat top punch, I use the same one for every bullet I cast & have done for many years.

yep a flat punch will work just fine.

once you make it from a simple [cut the head off] bolt it'll work for all sorts of sizes too.

Never thought of that, thankyou guys!!

that's why we get paid the big bucks round here... LOL.

And worth every penny to us novices!
