    Yea started at 57 since the manual I originally was looking at said 59. Anyway, the cases all look very similar, primers are not much different from one another, no noticeable bulging or expanding. I agree, I believe 58 might be the ticket here; tightest group as well. Didn't measure it but it looks to be .5 or less

    You will find that reloading manuals go up and down on their loads. Today in the liability world they are leaning towards lower pressures. I have a few manuals from 40 years ago that have loads in them that are way over max for today's manuals. Even my pet load for my .340 Weatherby is not published in any manual anymore and the ones that are listed are a couple of grains lower than what I am shooting.

    As for pressure signs I have a hard time trying to figure them out with the pictures and what else is published in the manuals. I went to measuring the cases in several spots with a micrometer to see what is going on with the case. The big problem with that is that all cases are not created equal and what load is save in one manufactures case is not in the other manufacture. This is where I try to buy enough new cases to reload instead of using a random bunch of them. On the random cases that I use I try to keep the loads a little on the mild side and have learned that sometimes those mild loads outperform the hotter loads.
    If you don't care where you are, you are not lost....

    I agree with theddguide on sticking with the 58 gr. load. You added .5 gr to the 3053 fps (avg. vel.) load, which increased it by 19 fps to 3072; you added .5 to that load increasing it by 16 fps to 3088; an additional .5 gr was added, which increased the average velocity by 51 fps to 3139. In my book, it is time to stop adding and back down a notch. It does not seem like much, but that is three times your average velocity increase with the same .5 gr powder charge increase. Brass appearance and book readings mean little regarding pressures. If you want to know about pressure measure the case heads on your fired cases. Your chronograph is trying to tell you something. The 58 grain load appears the most accurate, and is certainly capable of killing a deer or an elk.

    Disclaimer: I only know enough about QuickLOAD to be dangerous... I did enter 59 grains of H4831 SC and came up with a pressure of 59,827 psi out of a Pmax of 65,000 psi. For strictly what it is worth, I could only go to 60.3 grains of that same powder to stay under 65K psi.

    This has been a good discussion.

    Yup I've pretty much ruled that powder outta my gun. Imr 4831 seems to produce much tighter groups so far
