I imagine you're going to be doing two passes for each cartridge. I'm a big fan of body dies (small base in gas guns as appropriate) and lee collet dies. They replaced it for me, no questions other than 'oh, how did you find that' and it was mostly two reloaders chewing the fat. I have received a toolhead that appeared to be cut off center from Uniquetek. Personally I don't see much difference in the performance. I've used both the floating and non floating toolheads. Does it matter ? Probably not but it satisfies my OCD. In my mind I'm doing the same thing there as I do with my optic mounts. I put forward pressure on toolheads when I tighten the clamps. I use the clamp kits and highly recommend them. I have nothing but wonderful things to say about it. This somewhat defeats the purpose of using a progressive but will produce less runout.īest advice is just to experiment to find out what yields the best results.

Some folks size there brass on a single stage press then complete the process on the Dillon. For my 223 I just use the standard Dillon Die set and it works fine and found that XBR 8208 meters consistently. I was experiencing too much charge variation and switched to a Hornady case activated powder measure which improved the situation. Run a number of number of pieces of brass through the charging station with the powder you plan on using to check throw consistently. Also installed a competition seating die. For my 308 loads, I switched to a Redding Type S die without the expander which seemed to significantly reduced the runout. I was using Dillon dies and isolated the runout problem to the expander. They did reduce runout somewhat but the biggest culprit was the expander ball being dragged through the neck after it was sized. I have Whidden tool heads for my 223 and 308 gas gun loads.
