Got this mod in my space age play since last October, but I cannot really use this cool turret on my space platform, for shell casing needs plastic, hence I've never build and use this mod. Maybe you can add a recipe that uses iron (or harder, copper) as shell casing? You can force player to put out empty case once the ammos are deplited, to make it into a logistic challenge. Right now it's just not as good as rocket launchers in space. And not as efficient as Tesla tower on the ground.

Coal Synthesis and Oil Cracking recipes can be used on Space Platforms, leading to Plastic production.

Good Luck!
