I have a new-to-me 1978 S&W 25-2 in .45 acp with .454 throats. Which diameter NOE expander plug would I need to load .454 diameter boolits? If I'm able to Beagle my 452424 mold to get .455 boolits, what plug would I then need? I already have the RCBS .45 AR crimp die I'm going to use. Any advice will be appreciated. GF
