Lyman top punch with the biggest cavity

[Don1357]

I need to make me a top punch for a 457130 boolit (45-70 collar button). Which Lyman top punch do you think has the biggest depression? I figure if I'm going to make one with the epoxy trick I may as well start with a honest to goodness top punch.

For most of my flat nosed pistol bullets, I just use a flat top punch. You can turn one out pretty easy from aluminum round stock with a drill, hacksaw and a file.

Use Lyman #374
(The Collar Button had a peaked/round nose profile and cannot use a flat)

I recently had to order a specific one for a RCBS mold.
I can't remember if it was from Midway or Natches Shooters Supply.
One of them has a chart with all their molds and listed with them is the right top punch.
