[QUOTE="AJ Peacock, post: 227836, member: 4885"] Some reloaders measure the cartridge and watch for excessive stretching. This has been statistically shown NOT to be a good indicator of pressure. It is more an indicator of brass alloy and how much the brass has been worked in the past. Others will point to primer pockets opening, same issues as above. Some will watch for ejector marks and load ammo that is below that level. The amount of flattening and cratering of primers has been pointed to as a good pressure indicator (even though it can really be a sign of other things, like firing pin spring strength, primer softness, firing pin hole clearance and headspace issues). All of the above 'CAN' be signs of pressure and they should ALL be watched. In my opinion, the best thing you can do is shoot your loads over a chronograph. Do some research and get an idea of the velocity you should get for your '06, barrel length and powder. Then you will know where you are on the pressure/velocity spectrum for your combo of components. Hope that helps, AJ [/QUOTE]
