I am kind of new to reloading. I used to use a lee classic handloader but now have a press. With the handloader it was very time consuming to get perfect seat depths, not just because bullets are man made objects and therefore are not 100% uniform, but also the fact I was using a mallet to seat it. But even with the press and the die set tight I still manage to under seat or over seat and have to constantly "baby" the depth into place. How do you more experienced loaders get the depth perfect without growing older trying?
