I have a Lee Pro 1000 that I am setting up, but when I try to get a specific charge weight it seems to jump .2 -.3 grains when using the powder disc size to the next size up. I saw that Lee sold an adjustable charge bar that replaces the disc and it is suppose to help make more precise powder charges. I was wondering if anyone uses one or if any place around OKC sells them. While I on the Pro 1000 does anyone use the bullet feeder and do you like it?
