    I was wondering if anyone has figured out a max load for 243 using a 105gr Amax and H4350.
    I am shooting a stock SPS Varmint. I think I have them loaded pretty mildly right now with 37 gr. of H4350. So whats the approximate max load?

    Thanks in advance,
    Sid

    Only way to know for your gun is to work up to it. Load until you see ejector marks then back off .5 grains.

    Your reloading book should give you some expamples. THe Ejector mark is the mark left on the case head where the ejector was on your bolt face. Usually a bright mark but not always.

    JUST BECAUSE ONE GUY CAN SHOOT A PARTICULAR CHARGE DOESN'T MEAN YOU CAN!!! you have to find out for yourself. Think about it... maybe his scale reads a grain heavier than yours, or maybe he is using better brass, maybe his freebore is more... lots of things contribute to chamber pressure.
