Not yet, I am not desperate as this is for a future build. I am trying to decide amongst several different wildcats based on brass availability, one choice uses the 300 SAUM as the parent case, the other 270 Win. Both end up as 6.5mm, just trying to figure out what my choices are for GOOD quality brass, and no I am not afraid of the work involved with forming the cases to their final dimensions, that is what long winter nights are for!
