Sizing down cast bullets .410 to . 401

Here is a .410-285ge WFNGC that I sized down in 3 steps
.410-.406-.401 ALL rcbs lube sizing dies, I lubed the bullet in the first die (410) that way it was slick enough to squeeze into the 406 then the 401 dies. The bullet on the right was taken out of the shoulder of a BIG hog ( 260-280 lbs), it still weighed 262 gr, bullet hardness is BHN 12-14
Bullet - before and after
BIG hog- Awesome cutters
