I have a .300 win mag and am working up loads and to start shooting 600+ yards hopefully out to a 1000 yards if i can find the place to shoot that far. One of my quetions is i had bought 300 pieces of remington brass and did prep work ie: primer pockets flash holes neck turned etc. and can only come out with 50 pieces of brass that are all within 1 grain of each other. This might by okay but i would like to get the consitency a little better. I have chronographed my loads and velocities show inconsistence due to brass.I hand weigh all my loads so i know that is consistant.Does any body recommend any other brand of brass? My other question is does anybody know who makes a die that will size just above the belt. I have found Innovative Technology makes one and am wondering if anybody has used one or any recommendations? I am kinda of in need of a die that will take care of this problem beins i have shot this new brass 3 times and am noticing some will not chamber anymore unloaded. Am i missing something or any simple solutions. Any info is greatly appreciated.
