Power of P-08 ammo in the 1920's

[SIGP2101]

Prior and during WWII nitrocellulose powders were used on all sides. This particular two component gun powder by today's standards would be considered slow to medium burning rate powder. (remember the flash at the muzzle)
Today's modern powders are fast and too snappy for Lugers. This is where most of the problems with P08 originate. Weak springs and out of shape other parts of P08's contribute even more to incorrect functioning of the Lugers. If you reload start with proper burning rate powder. Then trouble shoot other components of the device. Using famous white W box 9mm is not way to go with P08's. 124 grains jacketed and slow to medium BR is proper way.
Tweaking a Luger to the off the shelf ammo of choice may be doable but something will give.

Hi:

Though some may consider us insane, I agree with your statement above completely!!

Here are some excellent powders I've used to create some outstanding handloads.

FMJ Loads: SR 4756 and Power Pistol

Lead Loads Accurate #5

All are with 115 to 125 grain bullets.

Sieger, what slow to medium burn rate powders do you recommend for 7.65mm loads? Thanks.

Good to know that I am not alone in this cruel world.
