I size the nose of an 8MM Lee bullet to fit a 32 Winchester Special. It would not chamber in the 32 so what I do is put the Gas Check on and size and lube normal using a .321 sizing die. I then use a .310 sizing die for the nose. I then use a top punch for a flat nose bullet. All you have to do is place the bullet nose first and hold the bullet until it starts into the sizing die. the bullet will center it's self as you push it in. I run the bullet in only as far as needed. I think I only run it in about 3/8 of an inch maybe a little more. This method makes for a nice bore rideing bullet. You can also size the nose first and then do the normal sizing and lubbing.
