[NSRCA-discussion] bullets

[Ronald Van Putte]

Good stuff Verne.

I have noticed the difference in bullet connector design.  I used to  
buy 3.5mm bullet connectors which had a "bulge" in the center of the  
male part.  Recently, I noticed some 3.5mm bullet connectors which  
had no "bulge" in the male part.  They push into the female part  
because there's a chamfer on the tip of the male part, which  
compresses the slotted male connector so it will fit into the female  
part.  The big advantage of this design is that virtually all of the  
connector is mated with the other half, unlike the ones with a  
"bulge", which have significantly reduced contact area.  Then I  
noticed that you can buy this same design in 4mm, 5mm and 6mm bullet  
connectors.  My opinion - these are far superior.
