Factory 380 HST Specs

[SVT28]

I picked up some 380 HST pulled projectiles from American Reloading a few weeks back and I plan on reloading some this weekend. Does anyone have the factory COAL? Also, I assume since the projectile is 99 grains that starting at the bottom of suggested charges for a 100 jacketed projectile is where I should kick things off?

I'm loading for an 85BB and LCP Max.

Thanks!

The 9mm 147 HST is the same OAL of most of the other JHP brands, like Speer and Winchester.

If possible make a few "Dummy loads" with short and long OAL's and do the plunk test, in your pistol, to see what works out.

Just remember short OAL increases pressures and too long may not feed properly in your pistol.

Good luck with a great 380, style, SD bullet.

I just measured a factory .380 HST and the OAL is.940" It really makes no difference what you are going to shoot them in, just use book data for 100 Gr. JHP .380. If it were I, I would just use the maximum 100 Gr. charge in the books and be done with it. I would probably use CFE Pistol as it is a good duplicate for Unique.

I don't shoot a 380;

in my 9mm and a berry 124 THP bullet at 1.075" OAL
a full load of CFE did 1222fps
a full load of BE86 did 1233fps and
Unique at 1.13" OAL, to get more powder, did 1212fps.

With a 147gr plated RN bullet BE86 powder made Unique powder, "Blush"
with the difference in fps gained.

CFE can get high fps but it also comes with higher pressures.
One reason the Hodgdon data site, keeps it low.
