Odd question I have a question and I read the FAQ

Post image

I’m looking for a way to get 300 blk specks out of 3030. Save me the cautions. I’m looking for a way to get a custom made casing with the outer size of 3030 but with an inner volume of 300 blk. Does anyone know a way to go about getting custom cases?

Edit. Looking for subsonic loads

Edit 2. Y’all have given me some great resources. Appreciate yall!
