Through unforeseen circumstances I wound up with 16# of Hodgdon titegroup, aka Highgun. Looking at 12g pressure data, the burn rate looks close to Green dot/International, so I made up a 3/4 oz. 20g load and sent it to Precision.
20g AA-HS
Cheddite 209
11.8 gr titegroup
CB 1075
3/4 oz lead
8 fold crimp
Velocity Pressure
1. 1205 9960
2. 1204 9690
3. 1199 9920
4. 1192 9440
5. 1195 9520
6. 1194 9520
Ave: 1198 9675

Titegroup is very dense, so crimps will tend to be dished; this was mitigated with minimal wad pressure and deep pre-crimping.
Enjoy.
