Yes,
I did one a few years back.
Easy enough. The slot is very very rough and could do with a file.
It’s very easy to go over power as the 300 and 400 were made initially to run at higher lower levels and de tuned for the uk.
I used a standard spring from chambers, re lubed and filed the slot and was on 11.4 before it settled.
Very simple to work on, but it can be easy to round screws.
Chambers has an exploded diagram that may help you.

The 300 is a doddle to strip, very well made inside no plastic!
Which or what slot are you referring to Rhys that requires filing?
Be prepared to shorten the Titan spring a bit, they are a bit of a source rather than a drop-in part, try it unaltered but don't be surprised if the gun is doing 15ftlb's before adjustment. If the Cometa 300 is the one I'm thinking of, it'll happily go as far as you let it, but if my failing memory serves me they're a piece of pee to work on.
