Pulled a bunch of rounds that were 144 Berger Hybrids in Virgin Lapua brass. I pulled the rounds and want to reload them with Berger 140s. Will the neck tension be terrible if I just reloaded or do I need to resize? With new lapua brass I just open box and reload, not sure how much already seating a bullet will matter? Thanks in advance for help
 
See if a bullet will drop in under its own weight or can be pushed into the case with minimal force. My guess is it will and you will have to resize. I always resize after pulling as it eliminates any variance or potential issues
