I’m testing a new 9mm load using HP-38 with a 124 grain bullet.
According to the Hodgdon website, the max charge for this round is 4.4 grains. I started at the min and it wasn’t until at 4.4 grains, the action cycled ok. But even at 4.4 there was a FTE about 1 in 30 rounds.
At 4.5-4.6, the action cycles reliably.
I tested these rounds in a Sig M17, MP5, and Glock 19 and got the same results.
I haven’t had a chance to chrono the rounds yet.
Anyone have experience with this powder? Is my experience normal?
