I know this is all about the sizer die.
The facts: 4 cavity H&G #237 200gr lswc gc.
Awesome bullet and mould. Great 44 mag full house lower recoil bullet.
Alloy is 5lbs ww to 1lb lino.
Star sizer @ .430" and Magma lube.
After sizing .430" and gas checking there are some very minor scratches on the drive bands.
It just bothers me that the scratches are there.
I took a drill and a brass 45 cleaning brush and spun it in the sizer die. Ran it for a couple of minutes.
I shot 1000 rounds of cast 45acp like that and it didn't seem to hurt a thing.
How to get clean the die to get rid of these annoying tiny scratches on the bullet so they are not there after sizing?
