Is there a standard sizing method for ball links RC

Is there a standard sizing method for ball links RC

Feb 16, 2013 Both of these turnbuckles have almost exactly the correct length I need. I hope their diameters are close enough to the 2.2 mm size the KDS 550 links are sized for. However, I am open to trying some other mfrs links. If their dimensions support my requirements. eg 2 mm rod with 5 mm ball. for the 31 mm turnbuckles 2.5 mm rod with 5 mm ball.

If that doesnt solve the problem, expanding the case necks on the UP stroke of the press often does. First, size all the cases with the decapperexpander rod removed from the die, then replace the rod and push the cases up over the expander ball. The case is then supported squarely by the shellholder, and the necks tend to stay straighter.
