Choosing the “right” barrel length.

OBT node prediction could potentially reduce development by a 30sht ladder.
You have to fireform cases and determine best seating and measure MVs (to calibrate QL) anyway. You'll have to validate predicted nodes anyway.

If you load develop for many bullets with the same barrel, then removing 30sht ladders with OBT could be nice. And maybe OBT would be easier than ladders for some.
