[QUOTE="MagnumManiac, post: 352433, member: 10755"] It [U]IS[/U] important that you keep your brass trimmed to below [U]MAX[/U] length, it is a safety feature of the brass. Now, you probably won't run into trouble until your brass grows to around .020" over max length, but not always! I have a couple of rifles that show 'crimping' when they're only .005" past max length! This is why it's recommended to trim your brass .010" [U]BELOW[/U] max case length. 30-06 brass tends to stretch/grow quite a bit on each firing, so it's wise to check them often, you can trim [U]ALL[/U] your brass to min spec when you get it, no matter what the initial source. I normally fire new brass first to iron out any shortcomings such as growing longer on one side and the like, then trim to MIN spec (.010" below MAX.). 2.490" for 30-06 brass is MAX, you really need to trim them back to 2.480" to be on the safe side, the brass you have that measures 2.509" is way over max and needs to be trimmed! If you do not understand the reasons for this, get yourself a modern reloading manual, they will explain why it's necessary in detail! gun) [/QUOTE]
