This is a great way to check if your seater stem is closing the tip of the bullet. Frankly, I will be surprised if this is the case since reloading tooling manufacturers have been relieving the area where the tip could bottom out since the VLD bullets were introduced in the mid 80's.
Seating stems that are not "VLD" seating stems can leave a ring around the nose because the bullet is contacting the die on a fine edge rather than a shaped flat. The VLD seating dies are shaped to push on the bullet over a wide area. It is unlikely that your stem is touching the tip of the bullet unless your dies are older.
The thing to keep in mind is that you will learn if your seating stem crushes the tip of the bullet to some degree but the fact that it doesn't (if it doesn't) won't matter if the closed tip is not the cause of no expansion. This must be determined. If this is
the cause, it is far more likely that you didn't do anything to the bullet to cause the condition of a closed tip.
