Hi, thanks for your response. Could you elaborate on what part of this is "extermely dangerous?"
Simply adding a flash hole should not disrupt the structural integrity of the case.
Also I feel the idea that steel cases are not reloadable is a misconception. There are many people reloading steel, it works well. Just like brass you have to inspect it between loadings. I have reloaded my 7.62x54r steel cases 5 times so far without issue... still counting.
