Here is some of the interesting stuff I come across in South Africa.
The guy quotes energy etc which we are fully aware of but overlooks construction of material.
Anyone got any advice or further come backs?
On a purely mathematical basis, I do not see an immediate problem with his argument:
400FPS w/ .20g BB = 1.5J = 400FPS w/ .20g BB
...so whether you have A=B or B=A, it stays the same. As long as you are not transferring more than 1.5J of energy per shot, you are still, technically, within the legal bounds. Caliber should not affect it... Although, reductio absurdum: firing a needle of .01g at 1.5J would probably not be a good idea.
Ultimately, instead of freaking out about how "blatantly stupid" this guy is, I suppose some testing would be needed?
*EDIT: makes more sense this time around...
From my mind is not 4.5 mm air pistol ammo? And therefore metal not plastic?
Correct, 4.5mm Daisy is usually metal. Two question remains though:
1) How much of a safety difference does a change in projectile material make?
2) What is the "minimum" caliber below which 1.5J of energy becomes dangerous? (as in my example above, a .01g projectile with 1.5J of energy)

Sorry John, by letting what is an air rifle into an airsoft game opens you up to all sorts of liability, which is "stupid".
I posted this here to see what the views of the guys on the other side of the water were, as they do tend to have more experience and possibly exposure to various aspects.
I seem to remember that the UK's testing to determine 'lethality' (the ability to inflict injury, not death!) of air guns that was done donkey's years ago - and was how the 1J figure came into being - was conducted using airgun darts. I'm not sure why the pointy bit of metal wasn't factored in when it came to applying the data to round plastic airsoft pellets as I'd imagine, all things being equal, a sharp point is going to break the skin more easily than a round ball.

Darts fired into a piece of wood to IIRC, rather than ballistic gel.
I'm pretty sure it was a pig carcass?!!
