DAM Hoser!! So it looks like your the man when it comes to Dillon machines so if you don't mind I have a question. I am having an issue getting the same OAL with my new XL 650. What is considerd to be an acceptable variance? For example if I am loading for an OAL of 1.125 and the rounds range from 1.122 to 1.128 is that ok? My thought is since I set it up as 1.125 every one should be with in .005. I do have the billet tool heads and I used a kit from Unique tech to bolt them in place instead of just using the pins to keep the tool head in place. FYI I am a newbie loader.
