Do not force them on the small tube. If you needto, use a piece of rolled up sand paper and give a few turns inside the oversert. (ifyour overserts are too tight, please contact MK Machining for feedback) Go slow, youwant it snug, not tight. This is due to the small tubes having some variation indiameter. We went this route as the looser fitting tubes would slide forward andbottom on the glass keeping powder from dropping. The overcerts have a positivestop built in them; you should feel them stop as you push them on. Slight resistance,minimal force to slide on.The tubes are numbered 10, 12 and 18. #10 is for magnum / large kernel powders likeRetumbo / N570. #12 is for powders like Varget and H4350. #18 is for ball powders.For the #10 and larger powders, you will need to turn down the Bulk speed to 3 or itwill dump too fast and build up on the overcert creating an overthrow. If 3 is stilldoing this, go to 2. It does not make a huge difference in overall time for dump. Weare seeing 12 to 15 seconds with larger powders.The calibration is important as you want to see the small tube as close to .2 aspossible. I set my limits from .19 to .22. So, as long as it is there, you are good to go. Ifthe shim gets you to a .18 or a .23, you can use the scales level feet to tilt it up ordown. I have had the bubble level at the very top of the level circle and the scale ranfine, it does not have to be dead center, so don&#x2019;t be afraid to use the leveling feet.On to the settings:Bulk is the large tube. I have found this works best at 6, 7 or 8 depending on thepowder. Just play with it. Most of mine are set at 6 or 7.Transition: This one can be a bit trickier; you must pay close attention. It is thetransition weight where the scale goes from the large tube to the small tube. I setmine normally at 2.5 or 3 and with bigger powders like N570 or Retumbo 3.5. This isbecause, if you watch the transition, the large tube will slow at the 2.5 transitionweight, but as the small tube comes up to speed, and the large tube rolls back duringthe transition, there is a rather substantial powder dump, so you must watch thescale to see where it is right after this transition, where the small tube is running full Finish Speed: This is the small tube speed. Typically set at 4 to 6. The small tubemust come up to full speed for a brief second so the software can meter properly.This setting is influenced by the last setting, Buffer. Think of the Finish speed like theV3 settings. Trying to get the small tube to run at full speed with 1.5 to 2. Grains tofinish the load. Just watch the transition very close and you will see what I am talkingabout.Buffer: This is the most overlooked setting. Buffer is the weight per kernel. So, if youare running Varget, it is typically .02 grains per kernel. However, it takes a second forthe software to see .02, so I set it to .04. This tells the system to go to the super slowspeed at .04 grains from target weight. If this transition is too fast, it will overthrow.So, setting out a little farther helps keep the system from overthrowing. N555 isaround .02 to .04 per kernel so .06 is a better buffer setting. The bigger the powderkernels are the bigger the buffer should be. Double or triple the kernel weight is ourrecommended setting.An example of this issue is where the transition weight is not set high enough andafter the transition, the small tube is only .5 grains from target and cannot slow fastenough to hit target weight and overthrows.speed on its own. You want to see the scale weight around 1.5 grains from the targetweight. This is important as the small tube MUST come to full speed so the softwarewill meter and slow (based on settings) and not overthrow.<img src="https://attachments.gorgias.help/dY4gQxz8mDw2Wnv8/hc/984vj29omBxPKGOZ/2026021613-d414b822-1645-4cfc-b7bf-b7cd06fc8d47-952e9ad1-b085-4c5c-b0c8-01681dc8a36a.png" style="width: 300px;" class="fr-fic fr-dib">NOTE: The relationship between finish speed and buffer size is a balancing act ofspeed vs accuracy. The faster you go the more overthrows you will have. Theexpectation should be 10 seconds for a throw. My system with powders like H4350,N555, RL15.5 is running 8-12 seconds per charge with very few overthrows. I canmake it do 6 seconds but the overthrows will triple. Also, remember, someoverthrows are due to kernel size, not the machine. Illustrated below N160:<img src="https://attachments.gorgias.help/dY4gQxz8mDw2Wnv8/hc/984vj29omBxPKGOZ/2026021613-473d2b89-1e09-44bd-bccc-5cb1bba662e8-993f7f8f-5d06-4028-b43c-e00741f753e5.png" style="width: 300px;" class="fr-fic fr-dib">Make sure your scale is isolated and grounded if you can. (there is a ground on theback of the scale, clearly marked) Any other electronics sharing the outlet or powerstrip provides electronic noise to the scale and creates issues which have nothing todo with the V4 system. I highly recommend the scale be isolated and plugged into aline conditioner or UPS to provide a cleaner power signal.Hopefully this information makes sense and helps define the actual rolls thesesettings play. Don&#x2019;t be afraid to play around with the settings, HOWEVER, give thesystem at least 3 throws after making changes as they typically take at least one ortwo cycles to settle in. Thank you again and I hope this helps you get better and more consistent results.
