Hi All,
I am testing some 9mm reloads with HP-38. Currently we used my wife's Beretta PX 4 Storm Compact since I currently still have my LC9S Pro on lay away but I suspect that I may see the same slide cycling issue with my LC9S and my reloads.
Anyway, we were at the range today and with Blazer Brass 124 grain FMJ her PX4 cycled beautifully. We switched over to my 124 grain FMJ reloads that I worked up from Hodgdon's load data and we noticed that she would get failures to feed. Almost as if the loads did not have enough energy to cycle the slide all the way back so that it could strip a round and properly load it. I loaded five casings with 3.9, 4.0, 4.1, 4.2 and 4.3 grains of HP-38 as 4.4 grains was the max load. The max load with HP-38 produces a velocity / feet per second of 1,037 with a 4" barrel while the Blazer Brass data shows a velocity of 1,090 feet per second with a 4" barrel.
So my questions are:
1. Is it possible that the shorter 3.2" barrel of the PX4 Storm did not produce enough pressure to properly cycle the slide even at near max load of 4.3 grains of powder?
2. Should I go the max load of 4.4 grains which still produces a velocity of 53 feet per second less than the Blazer Brass.
3. Can I or should I attempt to go to perhaps 4.5 and 4.6 grains which is slightly higher than the Hodgdon max load due to the fact that the barrel on the PX Storm is 0.8 inches shorter than the Hodgdon's test barrel and the barrel my LC9s is 3.1" ?
