So far I have found that these DVD's are great! They cover some of the same areas his books cover, but often are presented with additional data, or with examples. I really like using the DVD's as well as the books. I wish they had put in chapter stops -so you can move to a chapter instead of having the scroll through the entire DVD. I also wish there was more Demo'ing, and less time talking in front of the big white screen. I just want some variety (the first Disk did this better than the 2nd).
Finally - this material is really about external ballistics, and dovetails with his books really well. Its not an instructional video on shooting positions - more like how to understand WHY you do the things you do when you shoot. From this perspective, I haven't seen another DVD that covers the same information. Again, these are more the WHY, while something like the SH online training covers the HOW.
