View Full Version : Head Space

11-18-2006, 10:25 PM
I got a Dillon 550 conversion kitfrom Al Newell when I picked it up he was insistant that getting the correct headspace on the 5.7x28 was of major importance. Ihave seen discussion on the board where it is said that its not such a huge issue.

So who is doing what and how?

If you haven't read it, this might help.

I would advise anyone new to reloading for the 5.7 to read this information at the Patent Storm.


This a description of the operating system. Pay particular attention to the part about, the ratio of L1/L2 is ammunition sensitive.
For proper operation of the firearm the ammo needs to be close to factory dimensions and pressure. YMMV. :)
