[QUOTE="nkyshooter, post: 1368296, member: 83787"] uh oh ... the worm can is open now! ... :) I've loaded/shot both with minimal neck tension and with 'more' ... I find 'consistent' neck tension to be the key. If you have a custom match chamber with a 'tight neck', you don't need much at all ... but in that case, you'll have probably had to turn your necks so they are both identical and matched to your chamber spec. If you're rifle has a 'standard' neck in the chamber, some tension is useful so that you get a more consistent buildup of pressure as the round is fired. For ammo we hunt with and for rifles we load by feeding from a magazine, I am a proponent of medium + neck tension so that we don't 'jam' a round home with the bolt and accidentally seat the bullet deeper in the case which could cause very dangerous pressure spike. My solution on my 260 AI is to use a 'light' neck tension from a Lee collet die but then I use a factory crimp die at the end to obtain the blend of tension and consistency that I perceive is 'better'. Right or wrong - my ammo / rifle combo is working so I'm not likely to mess with it much. :) [/QUOTE]
