Yes the nibbing is only draw out the OA length.
Then you still need to form the case in a FL sizer a;ong with the usual trimming to length.

Any of this drawing, nibbing and other drastic case elongation and sometimes diameter changes often rquires some equipment,,like a lathe and a very powerful press.
Not the norm for the average reloader.

I feel the same about lathe turned cases. They seem to work OK with BP loads from what I've read. Careful/watchful annealling seems to be one aspect of long case life.
Sometimes their cost per/case isn't too bad considering the alternative(s). But you often have to order a 100 or more. At even 6 or $7 a case, that's quite an investment.
