I am new to reloading. I just completed my first session of reloading for my Weatherby Vanguard stainless Sub-moa. I referredt to the Sierra reloading manual and am using IMR-4064 powder in Win. cases and 100 gr. Sierra gameking (for hunting purposes). The max load as per the manual is 36.2 gr. I loaded 5 rounds with 35 gr., 5 with 35.5 gr., 5 with 36.0 gr., and 5 with 36.5 gr.. I plann to shoot these obviously in 5 round sets. Is there a better way to find the best load for my particular gun? By the way all the rounds are 2.652 coal. Thanks.
