I guess we all start with Lee at some point, beginners. And they CAN cast decent bullets, but usually only by luck out of the box or after messing with them. A kit as some say. Wouldn't think it would be so difficult for Lee to make a mold that will cast bullets that will be sized by a Lee sizer of the correct size, but seems pretty rare. The .430 310gr that came in the mail other day, now it casts 430, but not out of the box. The 452 300gr that came at the same time, its going back. Not even close to 452, and you have to watch the alignment when it closes, make sure its right. Wanted 2 so I could HP one of them. But think will just save me alot of effort and frustration to just go pay for a good mold.
