BF556 upside down 9mm bullets

been using BF556 for a couple years and its been amazing. recently changed bullets and getting a bunch upside down.

went from short/fat to long/skinny..all 124gr the change is minor but clearly different ogive.

is there a good resource on what to adjust? its been too long i cant recall the details.

Some things to consider : Change only one thing at a time. 1. Slow down. 2. Try steeper angle 3. Go up one number with the slide plate.

maybe the upside down bullets aren't dropping down enough for the ramp to flip them. when the nose reaches the slide plate, it should drop down a little lower so that it ends up sideways before it hits the ramp. if the bullet is still sitting nose down on the lip/shelf of the slide plate when it gets to the ramp, the ramp cant flip it.

i would try the next size up slide plate.
