The Webley MkVI is probably my favourite airsoft gun. The only downside is that the shells are easily lost in the heat of battle if they get ejected so a solution is needed. I believe it comes in the form of this block of rubber:
Remove the blu-tac and…
A row of shells are embedded in it.
I removed these and could start casting.
There is going to be a bit of experimentation in the material used for these, first up a silicone rubber:
And the shells:
Then a plastic resin for a harder shell.
When these have been removed, I could clean of the flashing and drill the port through the centre.
These chrono’ed at 280fps with .20s, though obviously drilling a larger hole could be used to increase the fps. The rubber bullets chrono’ed the same but are a bit more tread-proof, though don’t eject as well.
Being white they are easy to see when ejected. In future I may spray the backs with a gold paint so that they look better when the gun is closed.
