So. With my 10mm witness mag. If you load it to 10-13, slam it onto your hand to essentially use Newton's law. (Object in motion stays in motion) to relevel the rounds. They end up sitting perfectly so you can finish off with 14. I also noticed by reverse loading. Taking out spring and dropping rounds in from the bottom. The guide literally sits at the very bottom with 14 rounds. So an extended bottom cover is probably needed since I'm not sure how close the follower should be to the bottom plate when fully loaded
