Extruded powder is problematic in ALL powder measures. Based on my experience, it is LESS problematic in a ROTARY type measure verses a sliding bar powder measure. Also, I have not experienced problems with long rifle cases and 1/2 indexing. However, I have never loaded 300WSM. I have only loaded 223, 308, 30.06 on my LNL. I personally feel the 1/2 indexing is one of LNL's strong points.
Red & Blue BOTH have superior Customer Service. But, I will say Blue set the standard for others to emulate.
