Reloading HST Federal Bullets

[kramer]

I had 300 rounds of HST in .40 so I pulled the bullets with the idea of loading them up for 10mm. The are 155 grain but they have a cannelure towards the bottom of the of the bullet.

Any difference on how you load these? Crimp any different?

Your cannelure will be well below the case mouth as you will seat o 1.2500".  The cannelure is there to secure the core inside the copper jacket.  Enjoy!

Also, testing indicates these probably won't deal well with the 10mm velocities, at least from a terminal performance perspective.  I would not expect to load them to max except for paper or varmints.

I agree with Shadow about the cannelure.

12.5 grains of Accurate no. 7 for a low flash, clean burning warm velocity load would be where I'd likely work up to. Would be about 1300 fps in a G20. Others may know better if that is yet too fast for this bullet.

If slower velocities are needed, the mid to high 9s of Accurate no. 5 would put velocities in the 1200s as would  low 9s of 800-X or mid 11s of Blue Dot.

I don't get the feeling that this bullet is made for full tilt 10mm. But if I were to play in thise velocities, I'd follow the old published book data and work up to 16 gr Accurate no. 9. A 155 XTP with CCI 350 ran 1425 fps in the 4.6" bbl.
