Ok just completed my AR. It’s a 224 Valkyrie. I’m in the need of dies. I primarily use Redding S type dies. My question is do I need to crimp on the semi auto? Or do I get the approximate amount of neck tension with the the proper bushing? If tension is the right answer, how much tension? Or can I just buy the regular sizing die? Anyone shooting precision ARs out there reloading and have any information I would really appreciate it.
