I will look for someone selling modified cases. buffalo arms has some [ but is out of stock currently ] that are cases modified to be 22 wcf - those should be usable.

I don't have a lathe or the knowledge [ I am a physician and good with my hands but not in this manner ]

I do have a friend with a lathe, and once modified the cases should last quite a while [ I really would like to make loads that are ballistic equivalent of 22 magnum at most ]

I was wondering it tip off mounts would work and I do have a lot of those [ they are in anchorage, and I am in isolation out here at the lake in the valley.. but maybe soon I can go to town and look for them ]

thanks again, you are knowledgeable and logical and practical
and that is the kind of advice I needed.
