Loading .380 Short Barrel Speer Gold Dots

[cvo]

I have the data on the Speer 3992 bullet, but I can't find any data on the 4020 short barrel bullet. Anyone know the difference in the Two bullets?

I would expect that the data is the same. the bullet co-efficient is .092 compared to the other bullet's .101, and that's the only difference in specs. The short barrel bullet will expand better at the low velocities resultant out of a short barrel...as compared with the regular Gold Dot using the same load data.

Look at page 918 in the Speer No 14 Manual: This is .40S&W data, but notice that it shows the exact same data for 80gr. GDHP and 80gr. GDHP SB (short barrel).

Thanks, I just checked that out and it does give the load data on the .40

You're welcome....but just to cover my butt...please don't use the .40S&W data on that page for your .380, use the regular .380 GD data on the .380 GD short barrel...

Murphy sucks.

I sent a email to Speer, lets see what they say.

Try

7625 powder, in the .380 with lighter bullets it is amazing and clean. Serria has listed data for it for years.

Speer got back to me and said " Use the same data as 3992 bullet".
