    220gr 357 Magnum Loads Experience?

    I have a new Mihec 359-220 that drops at 216gr as a HP with my range scrap alloy. Intended for 358 Winchester and 35 Whelen.

    I am going to experiment with loading long and using these single shot in a 357 magnum Winchester 1892, 20" barrel. They chamber smoothly and engrave rifling about 0.050" when seated at the crimp groove in 357 magnum brass. Ignore the ugly wrinkles, mold isn't broken in yet and was too cold.

    This borders on the realm of -why would I do this, I have a half dozen good molds for 357-, and the answer is "because..."

    I referenced an article on the 358627 courtesy of Mr. Glen Fryxell on the LASC page:
    http://www.lasc.us/FryxellLyman358627.htm

    The MP mold gives more case capacity than the 358627, but this is a base of reference. Not much published in my manuals this heavy. Hodgdon online data for rifle doesn't go snow above 180gr. I don't plan on nuclear loads and I'm not trying to make it into a 357 Maximum, though the 20" barrel ought to give respectable velocity. Standard caveats of start low and work up apply. Any one else try going this heavy in 357 mag?

    When I was shooting IHMSA, I loaded a cast RCBS 210 gr .35 Remington bullet in
    my .357 Freedom Arms revolver. I did pretty well with that load for a number of
    years.

    I'm loading a round similar to the one above Using a 240gr. 35cal. bullet from a Saeco mould #363 I think. (sold the mould) These are to fire in my long throated 357 Handi rifle I'm starting with what I believe will be a sub-sonic. Kind of a 35cal. Blackout. We'll see how it goes. Gp
