Since our club uses an e target that measures velocity I thought more about using this feature.

I moderate a 223/556 specific long range range group with over 5k members. When looking for a "node" or course a wider node will be most forgiving with a larger margin of error.  The case capacity of a 223 is so small that the powder charge is very critical to hold a tight waterline (vertical dispersion) . In F-Class at the national level, one 9 will cause you to lose the match. In long range, 1000y, they are cleaning with a 223, it comes down to X counts. Most load to .02 grains of powder weight charge with a high quality scale. My 20 string ES is single digit weighing to .02gr. I don't see how a thrown powder charge will ever get close to that. In SR the target is much larger but still holding a tight waterline will keep you in the middle of the target which would allow you the widest margin for wind call errors.

Reminded of tuned scales by this guy Scott Parker.

I've been throwing charges with my Lee Auto Drum mounted on a Dillon and shot 600 with 77 Noslers loaded to mag length. I lost a bit to wind and had to come up a couple MOA for elevation but not too shabby.
