Just a quick google leads to 6mm “match” bullets for roughly the same as 6.5 stuff..if you know where to look..
Brass..gonna need a bunch , either at factory ammo at a buck a round or brass pieces at .65 cents a pop. Plus primer plus powder..

You aren’t doing a 6mm wildcat any less then a 6.5 ..

If your looking for a new caliber/build then sure I see it.. there will be a fad but how long? Look at the Valkyrie , it was the shizznit..till the next wildcat round came out

You can push a 90gr-107 gr load in a grendel at about the same..so
