A few Japanese companies now offer soft tip barrels in No 5 tips.
Supposedly it's "about 1.6mm thinner than 2BA."
Here is a picture for reference.

The idea behind is it allows more barrel tungsten near the point/tip so it gives the soft tip dart more of a steel tip balance. Less plastic = more tungsten
Also, the No 5 metal conversion tips are almost like a steel tip....you can really see how thin these are when comparing these to the picture above.

I'm going to have some steel tip darts converted to soft tip and want to go with No 5....figure it would be easier since I like darts with a more cone shaped nose and a No 5 tip will require a smaller nose section for drilling.
Anyone know the actual No 5 thread size?
The 2BA thread is a 4mm tap size....so a No 5 "about 1.6mm smaller" puts it's around the 2.35-2.44mm range
Closest I can think of is 3/32 which equals 2.3813mm (which is roughly 1.6mm smaller than 4mm)
I thought the No 5 thread tips started in Japan....why would they use imperial/standard sizing? That make sense?
