AR15 , then you want to full length size them .
Some rifles with tight chambers not only require full length sizing but also benefit from the use of a small base resizing die .
Semi-auto's have needs that bolt actions do not require .
Try a standard resizing die first...small base dies are "usually " not required but are available if needed .
