"...The brass mouth is flared..." Shouldn't be. Bottle necked cases do not get flared. They get chamfered on the inside of the case mouth.
There is no 'crimper' in a bottle neck seating die to fix a flared case mouth. That's for handgun and straight walled cases only.
"...don't really care about saami..." The case and die manufacturers do.
