Hey guys, I have the Redding two die competition set on back order right now from Midway. It's the comp seater and FL bushing die set. It's $233, for $180 I can get the Whidden set with the bushing die. How durable are the Whidden dies. It appears they are aluminum? Are the Redding dies worth $50 more? Up till now, I've always used standard Redding dies. This is my first time using micrometer dies. I have time to change my order if the Whidden dies are good to go.
