cartridge length : 29,6 mm
I measured the velocity of ten rounds and obtained the following results :
Mean : μ = 363,3 m/s
Maximum dispersion : dm = 18 m/s
Standard deviation σ = 5,1 m/s
No signs of overpressure and good functioning of the weapon.

If I had access to those components(bullets/powder), I would surely give them a try.....but I don't. Any reloader that can produce reloads that function 100% in HIS Luger, has accomplished something.

I worked for many months before I found a combination of powder, bullet, OAL, etc. that my DWM liked, and would function with. When I get, and fit my new BarSto barrels in 30Luger for my Colt Defender, and Browning Hi Power, I will most likely have to start all over again on a new recipe for them. I don't think that they will be as temperamental as is the Luger.
