I have a Shilen 22-243 and they made it a .250 neck. So when I turn the necks down far enought to chamber, -.001 at a time. I get it as close to perfect as I can. After shooting it my die just barely touches the case. I need the die a little tighter. Any Ideas about what I can use to get it to work. I was thinking a lee collet die. Just because it it a 22-243 win, no shoulder angle change. I didnt realize shilen's default neck would be pretty tight. I have ruined 20 Norma brass and 5 Nosler custom brass trying to get it to work right..
