[QUOTE="jpickar, post: 1818967, member: 105894"] All you should do is expand the neck. Then load cartridge to fire form. The nosler reloading manual has a good write up on how to fire form under 280ai section. The neck/shoulder junction on an Ackley cartridge is 0.004 shorter than its parent cartridge. You are crushing the case which is why you have uniform dimping around the entire shoulder. Also due to chamber/reamer/go-guage&no-go gauge tolerances i would start with new brass. If you have to use once fired, I would full length resize the once fired brass in a regular 25-06 die Then expand it up to 6.5. Then fire form. Feel free to PM me and I'll give you my cell and I can walk you through it [/QUOTE]
