After you have swaged all the cores, the lube must be removed to insure a tight grip on the jacket when the core is swaged inside of the jacket.
Place them in a clean container until you are ready to form the point on the bullet.
Now comes the tricky part of swaging your bullets. If you have exercised good quality control and annealed your cases properly 99.5% of your bullets will turn out looking really good without the nose folding upon its self. When you are ready to form the point remove all lube near the mouth of the case where the point will be. If you don’t it will cause wrinkles on the point. This will make a very nice hollow point bullet. If you have a lead tip point forming die, you can run the bullet into the die just enough to force a little bit of lead out the end.
This is an update. It shows the gradual forming of the point of the bullet. This is what happens inside the die that you don't see.
When you have finished with your bullets, now is a good time to put them in the tumbler to make them nice and shinny.
