I am having great difficulty in obtaining a good black and white print from
my Epson Photo 830 inkjet.
I have tried printing the B+W print in RGB colour mode which produces a good
quality print although there is a slight colourcast.

I have also tried printing with the black only option in the epson control
panel. This produces a great black and white but then the print looks very
speckled (like a low dpi printer) is this normal when using the black ink
only mode?
 
NOW DA SPAMMER IS TALKING WID FRANKIE CRANKIE TRYING TO SELL HIM AN
INTEREST IN IS SPAM OPERATION.

This is a classic inkjet problem. You might be able to reduce it by playing
around with colour profiles, changing paper or even the lighting conditions
(natural vs artificial).

That's normal. In RGB colour mode the colour carts are mixed with black to
produce shades of grey. If you turn that off other tricks have to be used to
procuce shades of grey. A trick called dithering allows a limited range of
shades to look like a lot more shades. Example: 16 grey levels plus
dithering can look like 256 levels of grey but the image quality/resolution
can suffer. It's a trade off.
