They had the same problems when they were the round pellets. I had 60% of a bottle that were 10-20% off weight due to the chipping you describe. The bottom of the bottle was full of loose powder. I switched to the CleanShot (same folks, same clean burn)loose powder in the speed loaders and find it to be as fast in the field as the pellets were and I was finally able to "Fine Tune" my charge.
