Thinking about getting a PTX insert for my LnL powder measure's case activated powder drop for 9mm, which I'm going to start casting for soon. Would it be a good idea to get the 357 PTX for 9mm? I ask because my Beretta 92 that I'll be casting for slugs at .3562, I figure I need .357 diameter boolits at minimum, and I'm going to try to do .358 if I can get away with it. With that in mind, would the Hornady 357 PTX insert work better here?
