    What size primers are you using for your 357 max? I'm using IMR 4227. Will be using 158gr and 180gr bullets. Also do you have a pet load with this powder? Using MGM 20in barrel. Thanks in advance.

    I don't own a Maximum but the loading manual that's near by says small rifle primers. The manual is an older Speer manual No 11. A friend had a T/C Contender 357 Max and his biggest problem was case head seperations from his over max loads.

    On lesser loads I used sp mag primers ,but for upper performance loads use sr primers only , as a blown primer at those pressures ain`t fun for you or the firing pin bushing.

    Small rifle primers and try a Sierra 180 flat point silhouette bullet. Works great out of my contender.

    Rem 7 1/2 work best for me.

    looked my load up:
    Federal 205m primer
    22.0 Winchester 296 powder
    Sierra 180 FPJ .357 Silhouette bullet
    Shoots great out of my contender.

    Cci#41 are what I use with up to 30g of aa1680 for my TC encore with 180ssp bullets seated very long

    This is obviously an encore only loading

    The Hodgdon Load Data Site lists a Remington 7 1/2 primer.
    The new Hornady 9th Edition manual also lists a Remington 7 1/2 primer.
    Speer #12 lists a CCI-400 primer.
    Lyman #49 doesn't list data for the .357 Maximum.

    CC41's just because I have about 10000 of them to burn up.
