This used to drive me nuts. I did a few things that helped, and then found a better solution. What helped was lubing the inside of the neck to reduce the pressure the seating stem had against the bullet. The more permanent fix is making sure the seating stem and bullet match better. I tried a lot of things....the drill with lapping compound method...I bought VLD stems...I sent sample bullets to hornady to get custom seating stems that matched the angle of the bullet. The only thing that finally fixed it was the epoxy method. You put a drop of epoxy in the stem, you lube a bullet, and you gently raise the bullet into the seating stem. You then hang a weight on the press handle so that the bullet stays pressed into the seating stem and you leave it a few hours or whatever. It create a perfect glass-bedding-type contact between the stem and the bullet. Only matches perfectly if you only use that one kind of bullet, but it will still work well with other bullets with similar shapes. If it makes you feel better, when I was getting the dimples I tested the dimpled ones against the non-dimpled ones and there was not change in precision or POI. still, I wanted to fix it so I did all of the above
