[QUOTE="bob4, post: 1576558, member: 57171"] I always prep mine the same each time. Things like De-burring flash holes is only done once. I am not as stringent as some and maybe more than others. But these days my ES has shrunk considerably paying close attention to brass prep. Problem , as I see it with neck sizing only,here is this. Each time you shoot that piece of brass it grows just a bit. Changing volume in the case and fit in your chamber until it becomes hard to chamber. Now you have to full resize it. If you don't adjust your dies to only bump shoulders back .001-.003. ( personal preference) you'll bump them back so far that your pet load will not shoot the same. Not to mention neck may be different if your all of a sudden using a different die. So why not discover your head space for that rifle and full length size it each time just keeping the shoulders back just far enough to chamber nicely and making your brass/ammo the [U]same[/U] each time? Making it the same each time means it should shoot the same each time. Again it depends on your application and how accurate you would like/need to be. [/QUOTE]
