Barrel loading ratio for small screws: 50% or 60%?

We are plating small screws in a horizontal barrel and see tangling and contact marks at higher loading.

What loading ratio (by volume) do you use for:

• M2–M3 screws
• Small stamped contacts
• Parts with thin walls

Also, how do you balance productivity against part damage? A photo of your barrel and a description of the flight design would be useful.
