Revolver versus Pistol: same bullet, powder charge and seating depth

Thank You.

I got notice that finally my ten thousand WSP primers have the Permit to get shipped as well as the Beretta Pico 380 pistol for disguised conceal carry (in an cell phone Holster).

Would be glad if someone would run the data on post #39 through QUICKLOAD for pressure estimation.
 
TheGuyofSouthAmerica,
I ran your load in QuickLoad, it is NOT SAFE.

Lee 124gr .356" TC bullet,
4 grains VV N330,
1.0465 OAL,
= 36,700 psi (for reference, CIP max is 34,084, SAAMI max is 35,000)
Its also a compressed charge of 117%, which means actual pressure may be significantly higher. Compressed charges tend to burn much faster than non-compressed charges and no software can properly estimate that. Personally I stay out of compressed charge loads unless a reloading manual or powder manufacturer lists the exact load as safe.

The 1.050 OAL is still a compressed charge of 107% and still exceeds saami max by a few hundred psi.

I'm wondering why not make your cartridges longer, at 1.100" same charge pressures drops to a safer 32k, higher pressure does not equate to more velocity/energy.

For example, one of my ridiculously overpowered handload happened because i repeatedly increased oal, increasing case capacity for more powder without increasing cartridge pressure. Unfortunately its not 9mm so while you can adapt the concept you will not see this kind of increases.
Book Load Max- 335 gr bullet, 43 gr charge, 2.020" oal ~50,300 psi. some 2000 fps, 3000 ft-lb if i remember right
My Load- 335 gr bullet, 47 gr charge, 2.135" oal ~46,800 psi, 2260 fps / 3,800 ft-lb.
If i load at 2.250" which is close to cartridge specification max oal, I could theoretically get the bullet close to 2300 fps, 4200 fpe. But I don't see the point as the existing is more than satisfactory for plinking (blowing apart produce like if i packed it full of tannerite)

Over 1.085" OAL the round does not chamber.

I have it now at 1.050" OAL with almost no crimp.

Something is wrong. How are you supposed to get into the case 4.4 grain to 4.8 grain of the powder?

I realised one case had a mouth split. First case I had to throw away but that case may have as well 30+ reloads.
So I investigated and found my crimp had tightened from 0.377" to 0.374". Expansion die expands it to 0.380" for lead bullets.
The bullets seated to OAL of 1.050" and those gave a velocity of 1040 fps with 4.0 grain (roughly by Volumen) of VV N330 powder.


What about for an OAL of 1.055" ceteris paribus of above.
OAL may vary vastly from case to case and bullet to bullet.
 
Dear knapwon,

Thank you so much for running my data through QUICKLOAD.

After reading your post I IMMEDIATELLY proceeded to adjust the seating and crimping die.
The 9mm Luger is now 1.057" for OAL and 0.378" for crimp.It has almost no crimp and I assume the powder is not compressed and the whole load is out of dangerous overpressure territory.

Tomorrow I will chronograph These reloads.
