I am reloading for my 338 Lapua built by Kirby Allen, and finally broke down and bought a concentricity gauge. This was an unwelcome surprise. I see a .004-.006" runout when measuring at the ogive of the loaded round. Here is my process: Press is a Lyman T- Mag II turret press Full length size with a Forster FL die, ensuring inside of neck is lubed Trim to 2.711" on lyman universal trimmer Deburr and chamfer with lyman tool Prime fed 215M primers with hornady hand priming tool Fill with 92.1 gr H1000 Place Berger 300gr bullet as straight as possible and place round in press with hornady 338 Lapua shell holder Using Forster Ultra micrometer seating die Push bullet up into die. Once it contacts the seating stem, I gentley tap and rotate the round 4 to 5 times. I then seat the bullet around 1/4 inch then rotate 180 degrees. I do this a couple times until the bullet is completely seated at a COAL 3.870" After seated I use a Holland Concentricity gauge to measure. It runs from a few at .001 to the majority at .004" run out at the bullet's ogive. So far I am only using new Lapua brass. I haven't gotten to reload the fire formed brass yet. After full length sizing, the brass neck run out is around .001" with a few in the .002 range. I'll neck turn once I start reloading the fire formed cases. I had to adjust the seating stem by drilling out the center so the bullet tips will not contact the stem. It only contacts the ogive now. When I set up the dies, I run the ram up to contact the bottom of the die and tighten the die lock nut hand tight. Does anyone have a suggestion on how I should fix this. I know <.001 is the goal. Right now to straighten, I drilled a hole in a 2x4 and "bend" the bullet straight. After this, it's usually around .001" run out. Is this smart? Thanks.
