I bought a bunch of pulled 147gr HSTs from American Reloading, but didn't see a lot of load data out there for the HST projectiles, so I figured I'd throw what I've found into the void just in case it'll help another reloader out there who does a search for this.
OAL: 1.125" (same as factory OAL)
Primer: Federal small pistol
Case: Federal (case volume 13.8gr H2O)
Powder: Hodgdon Longshot
Tested in a Glock 19 with a Zev 4.5" barrel
Charge wt - Velocity (5 shot average) - Standard Deviation
4.0 gr - 802 fps - 19.6
4.3 gr - 860 fps - 17.2
4.5 gr - 885 fps - 16.7
4.6 gr - 902 fps - 9.4
Velocities were pretty underwhelming. I'm considering seating the projectile just a tad deeper. I was going off of Hodgdon's data for a 147gr XTP, but when I punch the HST measurements into Quickload, it's showing that I have more case volume than the XTP data which I think is contributing to the lower velocities.
I'd be very curious to see if any of ya'll have any data/chronograph readings you could share.
