After casting a thousand or so of these boolits, I finally had a chance to try them out...
I was kind of suspicious since loading to an OAL similar to factory am mo, there was a ridge in the case where the boolit expanded the taper, even after a run through my Lee FCD. It didn't hinder chambering in either my Blackhawk or the AMT Automag III so I loaded up 50 for testing.. Next will be accuracy testing at 25 yds in a couple weeks.
This boolit on 6.8gr Blue Dot is a great, fun load for the Blackhawk! I'm thoroughly happy I had the chance to try it, and the 2 liter plastic bottle that was jumping around the range seemed to be having fun as well!
If there's enough interest in another run of the mould, I'm definitely in for it!
