Go easy.... Was thinking of prepping a bunch of .308 and 6.5 Creedmoor brass, maybe 300-500 pieces or more - up to and including sizing and priming, and then just storing it until I need to finish loading(working up new loads, matches, etc.). Are there any problems with doing that? Does the sized brass spring back any amount that could affect neck tension or anything else? After 29 years of reloading, I should know the answer to this, but but it's something I've never tried it before. I've always charged cases and seated bullets fairly quickly after sizing and priming. Maybe 2 days in between at the most. I know sized, primed brass is available from sellers - but that doesn't necessarily mean it's a good way to go. Figured I'd asking before diving in....
