[QUOTE="dwm, post: 26609, member: 1136"] I have factory 25-06 REM and 7mm SAUM rifles. I was thinking of using 270/30-06 and 300 SAUM brass and necking it down so the case necks end up thicker therefore fit the factory chambers better. I have a couple of questions: 1. Should I start with 270 or 30-06 brass for the 25-06? 2. Can I just run 270 or 30-06 brass through the full length die and get 25-06 brass? 3. Can I just run 300 SAUM brass through the 7mm SAUM FL die and end up with 7mm SAUM brass? 4. How do I determine the actual neck dimmensions of the factory chambers? I will need to know this so I know how far to turn down the newly formed brass. 5. Do I need to make a chamber cast? Is this hard to do, etc, etc ... 6. Is there an advantage or disadvantage to having thick brass in a case neck? I know most competition tight neck chambers end up with thin brass on the case necks. 7. Are there a books I should be reading that discuss all of this? (Might keep me from asking so many questions.) As usual, an insight that you guys are willing to share would be greatly appreciated.
