Anyone have any experience with shooting the Dot Torture Drill? I’ve done it 4 times so far. I have been doing quite a bit of dry fire with the Dry Fire mag lately. Looks as though it is helping. I am trying to become proficient at the Dot drill as it is a prerequisite for a 2 day red dot class with the Modern Samurai Project that I aim to take this summer. So anyone else shot these?
