[QUOTE="Phil Rizzo, post: 3055582, member: 126313"] The Hornady inserts aren’t famous for perfectly round holes. Beware. Always use the exact same insert, they can vary quite a bit even though stamped with the same numbers. Shoot the brass until you can feel tension closing the bolt on a fired case. Hopefully your first firing is a reduced load, at least 5% off published maximum charges for case life consideration. It may take more than 1 firing. Once all the cases form to your chamber length, the headspace measurement will be more consistent. Then try to bump the shoulder 1.5-2 thousandths, average. They should chamber like you need them to. Good luck, and remember it’s best to average measurements of multiple cases for a “target” number. [/QUOTE]
