[QUOTE="MagnumManiac, post: 1257447, member: 10755"] This is my take on NEW brass, if you run it as it comes from the factory, you will run into few problems. If the necks are out of round, or suspect in any way, I will NECK size them ALL to make sure neck tension is the same across all cases. In most cases it is within specs, even though they may not all be the same. What's important is that NEW brass ALWAYS moves the most on the first firing and rarely are 2 cases the same length from head to mouth. Now, I run brass twice through the rifle before I trim it to minimum length for hunting rifles. My comp guns get a different set of parameters, I run the brass within .010" of the chamber end, which I measure with a gauge. If you look at once fired cases, their lengths will vary quite a bit, even if you trim them first, this is normal, because the brass needs to find where it will stabilise after having all that work done to it in the manufacture of it. Some cases take more firings to settle than others, this is just a fact of reloading. Cheers. gun) [/QUOTE]
