I would expect that what you see, is an oversize bullet forced into a normal sized case for a jacketed bullet, it will expand the neck/case to the base of the bullet, and you will see a line at the base. There is some Trailboss data for 357 on Hodgdon website. A search for other data shows a lot of Trailboss info on 357. Main thing with it is, do not compress that powder in it.
