I used to use a volume measuring tool with pre-marked increments on it and a plunger to adjust volume. After shooting a lot, a friend and myself both settled on shooting "105" grains (based on this tool). As my friend has gotten into reloading all of his ammo, last year we decided to weigh our charges with his fancy new scale to increase consistency. We discovered that "105" on the volume tool was actually 78.5 actual weighted grains (777 ffg). I know that all powders have different weights but I was surprised at how inaccurate the volume tool was. Anyone else compared volume measurements to actual weight?
