[QUOTE="Cruizin, post: 218950, member: 7095"] Here is my input. I have a 338 edge ai and I have some loaded rounds that vary quite a bit. I use redding competion dies neck and bullet seater with no expander ball and, I neck turn and aneal cases but have many lots that I reload and not all are turned. I have to say that the neck turned cases have the least amount of runout but I believe the issue is in the bullet. Even the neck turned cases have issues but they do have better consistency, but it still leaves some to be desired. I am also using a forster press. I use sierra 300 smks and considering how much they vary in bearing surface (I've seen up to .015") I feel that a lot of the run out has to do with the consistency of the bullet itself. How round is that darn thing? It's a lot of copper and soft lead. How much does the point where the press grabs the bullet to push it into the case vary from the centerline datum? In other words how much does the point of the bullet vary from the centerline? Does anyone measure this with the sierra smks? I have heard Berger has made some new dies/tooling and their BS varies very little from bullet to bullet (+or -.001 or less). I sure wish they would make some 338 cal so I could try them. [/QUOTE]
