Some once fired military brass can be WAAAAAY oversized in the area where those splits occurred. Chambers are very generous or something. This brass is not a good candidate for an AI or substantially changed fireformed body.

I have sized TONS (literally) of this brass, and never had a single problem with it.

Next to Lapua and Norma, it is the best you can get.
