PP is for max effort 9mm loads imo & it is really loud. This could be why your accuracy is suffering or you are loading too small a charge & not getting uniform combustion. For midrange to full power, I prefer WSF or Unique, RS Sil. For light target loads, below midrange, just about anything that works in 45acp works great for 9mm minor too. I like WST, but RedDot or RS Comp also work fine with 147gr bullets. Some like TG, just not me.
