Cracked die?

[kwaynem]

I can’t tell if this die is cracked or has had a piece of brass with something on it cut a groove in it but every time I resize a piece of brass it cuts a groove in it

I had a die that did that and i took some 800 grit wet/dry sandpaper and a drop of oil and wrapped it around a dowel rod and chucked it in a drill and polished it out.

Is that a line of brass built up in a crack? Will the brass build up come off?

Awful straight to be a crack.

Looks like a burr that’s catching the brass

Sandpaper dowel rod like was stated.
NO dowel rod then take a cheap ink pen remove the guts and use the hard plastic outer tube as a dowel rod.
Cut a slit in it.

Or use a cleaning brush for rifles and wrap paper towels around it to fatten it and then wrap sandpaper around it.
Or just use paper towels and wet them with automotive polishing compound.

Not that you do not know all this already.
I polish all my dies to an almost mirror finish.
