1Akshooter,
Did some experiments years ago screwing up the tip of bullets. I could make them pretty ugly and convoluted, yet they continued to group pretty well. With a little care, I would not expect a problem flattening the tip of your Partitions.
On the other hand, a little damage to the bullet base will likely have significant impact on accuracy.

Imagine your grave on a windy winter night. You've been dead for 70 years.
It's been 50 since a visitor last paused at your tombstone.....
Now explain why you're in a pissy mood today.
