Gentlemen
I'm getting going on 44 magnum and am trying to figure out what top punch to get for a lyman 450 lube size.
The mold I'm using is an arsenal H&G 503 432-250.
Recommendations ??

it is very easy to form the top punch to fit the bullet using epoxy
Go to NOE. Look up a mould with the same nose profile for that caliber and order one.

Use a flat nose punch. It'll fit any flat nose boolit.
We go through life trying to make the best decisions we can based on the best infomation we can find, that turns out to be wrong.
Flat nose? I use a one quarter inch bolt. Works for me.

And then grind the head markings off.
Any top punch with a "V" shaped cup to center the bullet so it's square with the die. I make my own on my lathe.
A flat faced punch should be faced off in the lathe. An out of square face will force the bullet off to one side of the die.

i've always questioned the use of a flat top punch. my thoughts are that if the bullet is set into the top of the sizing die at a little bit of a angle; the flat top punch will start the bullet at a angle and not straight into the sizing die. maybe??
Lymans top punch number is 421, the same as 429421 and 429244. I usually just look for a punch that is flat and doesn't have any sort of lip on it and doesn't exceed the diameter of the main body of the bullet.

If the bullet is not straight a flat punch will touch the highest point first, putting all pressure on that high point which will push that point down first. As the bullet is rotated the pressure will lower from maximum til it is even across the whole point. In the case where the bearing surface of the bullet shank is very short, there might not be enough movement to fully straighten the bullet.

Spell check doesn't work in Chrome, so if something is spelled wrong, it's just a typo that I missed.
I can't help for the specific bullet. I use a Lyman 460 for my RCBS 44-250-K which has a .300 meplat.
