I have been using RCBS or Redding dies for a long time, but recently bought the Forster Ultra Micrometer seater die for 223 and love it. So, when I thought about 308 dies I figured I would try a complete set of Forsters. Question is I am reloading for one 308 semi-auto rifle and it looks like Forster has a "Full Length Sizing Die" or "Small Base Full Length Sizing Die", which one to get? I do use the RCBS small base dies for 223, but have read pros and cons - so, any thoughts on which Forster die to get for the 308?
