You have to be shooting very far, with an extremely accurate rifle, extremely consistent brass prep, temperature stability. Etc for small variations in powder charge to be meaningful. Especially at hunting ranges and animal size targets.
I like the cool toys too, and looked into a V4. If all I loaded was H4831/H1000 (long stick) and I did it a ton, or was shooting F-class maybe it would be worth it. But my thrown charges shoot fine at 600 in my hunting rifles, weighing/ trickling doesn’t improve it enough to see it on target in my experience.
Your needs may be different but I think there is a real misunderstanding of how little a couple tenths in charge weight actually matters on target, and how accurate the scales most folks use are anyway.
I really like the uniflow (with baffle and micrometer) for ball powders. The el-cheapo lee perfect for stick powders. Load up the block and charge 50 cases at a whack - case to case until they are all done before you set it down. It’s a real timesaver.
Ever shoot 10-20 shot groups at your max hunting range and check thrown vs weighed charges? I bet a lot of folks would be surprised.
