    I need some advice from those of you who load and shoot a lot of 357 Sig

    I have been loading 357 Sig for my Glock 20 with a threaded KKM fully supported, button bored,conversion barrel. I want to load some 147gr or even 158gr lead bullets to use with my supressor. Traditionally I used 125gr sj or fmj loaded to 950-1000fps. Most of the jacketed or plated bullets are .356 so I am being overly cautious

    Ive come across a source for 38 super truncated cone that are the correct shape and OAL..and have an OD of .357.

    Does any body have any experience with a high pressure load like this and lead lubricated bulletts, If so I would reall like to hear your experience.

    I've been veryfortunate. In th past20 years I've loaded 20,000 rounds of 125 grain 124 grain and had no KBOOM and only5 squip rounds. I sent a communication to KKM last week but have not heard back from them.

    All experiences are welcome.

    Thank You in Advance
    Don Lagarto
