Shocked over diff in 1 grain
I have seen it dozens of times and still shocks me how much difference a 1 grain difference inpowder charge makes.
I got .7MOA at 200 yards with 74gr of 7828 and 160gr accurbond with my STW. I got over 1.5MOA at 200 with 75. I see it time and time again. My 45-70 with 46gr of 4198 gets 1.4MOA over and over but over 2MOA with 48gr. Really makes relaoding seem worthwhile.
