If I was strictly using my ML for hunting, the only thing my scale would be used for is adjusting my Harrell's powder measure..........on the other hand, if you are really into long(er) range bench rest type accuracy, then scaling your charges is almost a "must!". The fact that even the best of the best ML bullets such as those made by Kyle Pittman and Dennis of Fury bullets have a relatively low (in comparison to CF bullets) BC and flat base, velocities need to have the lowest ES's possible. Equal powder charges and precise bullet to bore fit is essential. Since I am not hunting now, I concentrate on squeezing all the accuracy I can out of my SML so yes, I weight my charges. In three weeks I will be up in Kentucky bench shooting out to 400 yards for score and group. Killing a deer at 300 to 400 yards with powder measure thrown charges is a piece of cake but shooting a .668" three shot group at 300 is another story.....and, I have shrunk that to under 1/2" occasionally with weighted charges.
