You will notice the brass sizes much easier.Just put it on a swab or a paper towel and get to spinning it.I also ever so slightly enlarge the stem to get it to contact the bullet farther down from the tip as some of the pointy tipped bullets I was using were hollow up high in the tip.And many bullet jackets get thicker the farther down the bullet you go so less chance of making a dented nose on them.The polishing of the seater stem also kept the stem from sticking to the bullet.As you lower the seated round do you notice a slight  bit of tension like the bullet is stuck in the stem??If yes polish the stem.</blockquote>
