Yup, what I found. I am getting about what I want so all is good,The MEC bushing chart is only a starting point to find what bushing is needed to reach your desired powder drop. I've found that I usually have to increase or decrease one or two bushings to reach my goal, depending which powder I'm using. I do use a powder baffle but small bottle on all 4 reloaders. Needless to say, your scale will be your best friend.
If you are loading on a progressive, they will almost certainly throw light, as the published numbers are for a 600 jr, which gets 6 cycles per powder drop, thus packing the powder in to the bushing. A progressive really only gets half a cycle per powder drop.How accurate have you found mec bushings to be. I find them to be consistent but about a grain shy of what there chart says.
exactly right and the reason you need additional bushings and a good scale. You can be 1 or 2 grs over on one jug of powder and be on the other side by 2 or 3 grsSome powders can vary from lot to lot. When you open a new jug be sure to re-check your powder drops. JMO Colonel
