I don't understand everyone having issues with the V4.
I use it constantly, and it's quick and I only get overthrows maybe once 30 drops or so (which I could eliminate if I really cared or wanted it to run a hair slower). If it does overthrow, I pull out the cup, use a finger to grab a couple of kernels and replace the cup.... it's typically spot on then. I then flick the kernels off my finger back into the hopper. Takes like 2 seconds... no need to do another whole drop.
I have three presets... ball powders, small stick and larger stick...
"Ball" (Staball 6.5, Staball Match, TAC, AA2200), "Small stick" (mostly XBR, H322 & N133) and larger stick (mostly H4350 and Varget).
I make sure the scale is always perfectly level (using the bubble level), and the ball and small stick settings are just tweaked settings after doing the original calibration (mainly tweaks for speed). For "larger stick" I made duct tape shims to go under the front two pads of the V4 (not the scale). The shims are a 2" X 2" piece of duct tape folded in half to make a 2" X 1" piece. When I'm running large stick I stick those shims under the pad to get the small drop tube a little more horizontal instead of angled down. This prevents the larger kernels from "tumbling" out in clumps.
Once I got the settings correct and saved them all, I haven't done a calibration since. No need. I just throw the powder in the hopper, choose the correct preset and dial in the charge weight. DONE. The first drop takes longer because it has to get the powder down the little drop tube. After that, they are always fast like normal.
SUPER EASY.
Basically, the bigger the stick kernel, the more horizontal the little drop tube needs to be so it doesn't tumble out in clumps. The more horizontal the little drop tube, the faster it has to spin to make the kernels move. It all works just fine. For giant kernels, I bet 3 layers of duct tape shims would be perfect.
