This guy might be able to help many of you out. Small scale case maker, custom marking possible (when I discussed with him minimum batch for custom brass with custom marking was 1000pcs).
I hav handled and used 9,3x74r brass from him, in my opinion just as good as any other.
On my (very long and always evolving) list of projects I want to do is to build a rifle in 38Whelen.(A 375-06 with some improved form), I believe I can alter the marking of 35Whelen cases with the help of a smart friend with a mini CNC-milling machine. 5 becoming 8).
Can a small batch of cases be remarked? Fill original marking with some "chemical metal" and remark in a mill?
