I'm a bit confused as to why I need to full length resize brass that wasn't fired from my bolt gun even though it will chamber without any issue. As far as i can tell it's not a safety issue neck sizing only, worst case scenario is the round just won't chamber? Am I way off base here or is my assumption correct? I have always read that if it wasn't fired in your chamber it must be full length resized. Currently I have two model 12 savages in .223 and have been keeping their brass separate and neck sizing only but recently got about 300 pieces from the local range and tried chambering them with 100 percent success in my bolt actions. I began full length resizing and found that it took a lot of effort on my part and the cases were being lengthened by about 10 thou which seemed like an awful lot. I only did about 10 then decided I should ask around to see if this is necessary to do and also normal during full length resizing?
