My experience with PP in both 9mm and 45ACP has been good. PP works best when loading at higher pressures. I have not had good accuracy when trying load at the lower end. I use it in 9mm for 124GR JHP in my 9mm carbine. For 45ACP I use it for 230 JHP when I want to make a lot of noise and push them fast. It has a lot of flash and makes a lot of noise.
