Hello! I wanted to say that ive been looking for a mod like this for a while! however i am having issues in regards to loading it as its having issues finding the technology for castable railgun ammo? specifically with your ammo expansion mod, causing this mod not able to load as its a dependancy

Thanks for the report and I'm glad you like it.
The castable raingun ammo is in the "casting-railgun-ammo-tech", behind the "casting-tungsten-ammo-tech" and vanilla "railgun".

It could be that the dependencies for the latest Subversion are not yet updated, so I apologise that you have to catch them manually. For the next hotfix update, I'll fix that too.

thank you! and yeah its an error with game startup where its trying to find that technology and is failing to, but i hope the issue will fixed in the hotfix!

Then I have misunderstood you, sorry. Could you please be more specific, maybe even showing me the relevant part of the log (AppData/Roaming/Factorio/Factorio-current-log)? Have you updated all of my mods to the latest version? Thank you.

Hello! and sorry for the late response been busy as of late but here is the relevant part of the current log:
