Is there a significant difference between the two out of the same length barrel? Foot lbs? Penetration depth? How does an "excellent" .32acp loading compare to an "excellent" .380acp loading?
Thanks
Thanks
Where did this formula come from? The "one shot stop" data has percentages below 61.5% -- if they used that formula, there would never be a number below 61.5%RyanM said:The problem is, the "one shot stop" data is fabricated. Fictional. Imaginary. They are not based on actual shooting data, they are based on a combination of made up crap, and the "fuller index" equation.
0.0057 * energy / frontal area + 61.5%
According to the Seecamp link supplied by USP9, the DPX does NOT reliably expand in the 380, although these tests were done in water as opposed to gelatin. It was noted that they did not expand when shot through clothing.
According to the Godenloki site linked above, the Corbon 32 load fully expanded 100% of the time to .435 caliber while the Win. Silvertips fully expanded only 33% and partially expanded 50% of the time to only .386 caliber. Both rounds penetrated to just over 8". This means that the Corbon load would probably narrow the already thin gap between the 32 and the 380 (and the 38 in a 2" barrel) All these tests were done from a 2.7" barrel.
Accoring to the Brassfetcher site linked above, the Hydra-Shok 380 load fully expanded 100% of the time to about .46 caliber and penetrated to 12". The Golden Sabre and the Hornady XTP loads expanded to about the same caliber and penetrated to between 10" and 11". All these tests were done from a 2.75" barrel.
These ballistic tests seem to correlate very closely to the real world results from actual shootings where the 32 and the 380 (and the 38 from 2" barrel) are all really close with a slight advantage to the 380. The correlation in the results tend to validate both the ballistic and the real shooting data. Add the tactical advantage of smaller size and faster and more accurate multiple shots to the 32 side of the balance, and I still think the 32 is a better pocket gun, especially for anyone who may not handle recoil well.

I have tested the dpx and in the secamp IMO they do not work....they feed fine etc...but never expand with a clothes test and only expand a hair in bare water and then only sometimes.
Nowif ya want penetration use the dpx..they really go deep.
The dpx is much harsher as far as recoil compared to the GS.IMO
Here is a dpx gold dot test with the seecamp .380
