[QUOTE="mountainman, post: 491646, member: 30120"] I've never necked anything up, but I do neckdown 8mm mag brass to 7mm stw and 30.06 to 270. You do need to fireform the cases but do it with a reduced load to keep from over stretching or spliting the necks and to get the right dimensions. If someone gets ahold of my ammo and uses it a 8 mag or 30.06 and it chambers , then they shouldn't have any problems other then poor accuracy and split necks. After downsizing check your oal of your cases before loading, trim if needed. I turn my case necks also to get the thickness down and even if needed. I've also been pondering if I should anneal the cases because I've overworked the brass, still kicking that idea around. [/QUOTE]
