Hi. I'm totally new to hand-loading and need some help. I have a 22-250, 22" bull barrel. Using Winchester brass, Winchester primers, H380 powder with Nosler 55gr. Balistic tips. I just bought a Lee press loader with a sizing die, a primer removal die, a case length trim tool, deburr tool, primer case cleaner... etc. I've read the basics and lets say they are very basic. I'm trying to size the neck of the case prior to charging. But I don't know how to set the die distance or how far to ram the press. I also don't know if I should be resizing just the neck, or trying to resize the whole case. I also don't know how to get the correct overall legnth of the round with the bullet legnth itself longer than the factory bullet I shoot. Any help would be greatly appreciated. Thanks - Robert.
