FIRST TIME HANDLOADS FOR CALIBERS
« on: November 29, 2010, 09:25:47 am »
WHEN STARTING TO LOAD FOR CALIBERS NOT PREVIOUSLY LOADED, HOW MANY LOADS OF A PARTICULAR POWDER CHARGE SHOULD BE LOADED FOR TEST FIRING AT THE RANGE. 3,5,????? IN ORDER TO REACH THE OPTIMUM RELOAD. I AM IN THE PROCESS OF RELOADING THE 7 MM AND 45/70 GOV'T.

    For rifle, I do 5 at each charge. 

    For handgun, I load 50.  Reason being I am testing more than just accuracy and pressure with handgun, I need to run enough rounds to test function as well.

    Using the ladder method of load development, you only need one cartridge of each charge weight.

    You do need to be a very consistent marksman or use a shooting rest though.

    one shot per powder charge? isn't accuracy dictated by the amount of powder. why else do we as reloaders start at a low charge and then work up to heavier charges. I will note that the higher charge would be preferable and still have close groups. please explain

    The linked article explains it better, but here goes with a summary:

    The ladder method essentially consists of loading a series of cartridges with ascending powder charges in each cartridge, typically in .3 grain increments.

    You take the loads out to the range and you shoot them at a single target using the same point of aim. You note the impact of each impact. You should see one or two "sweet spots" where a particular range of charges results in a closer cluster of impacts. Your ideal load will be in the middle of one of those ranges that produces a cluster.



    Naturally you'll be watching for pressure signs on each load as well and if you see anything to indicate overpressure you stop.

    That method will get you close to optimum charge weight fairly quickly.  After that you play with seating depth to finalize as a general rule.  That, and chronos are cheap enough these days, every hand loader should have one and understand how to use it properly.
    This may be considered as the true palladium of liberty. . . . The right of self defence is the first law of nature: in most governments it has been the study of rulers to confine this right within the narrowest limits possible. Wherever standing armies are kept up, and the right of the people to keep and bear arms is, under any colour or pretext whatsoever, prohibited, liberty, if not already annihilated, is on the brink of destruction- St. George Tucker, Blackstone's Commentaries
