The idea that a free video is better than nothing is a bad way to look at it, exactly as stated above.
Rex did a very good job with his Keywords and Titling of the series, he made it search friendly. That still does not change the fact, it is just a poorly put together highlight reel with a voice over track. He is either reading directly from the Army TM 23-14 Manual which is very old circa 1994. Or he is using Plaster's Ultimate Sniper. Both are full of errors and cross platform contamination, much of which has changed over the last 15 years.
If you look at precision rifle shooting in blocks, Pre-9/11 and Post 9/11 a metric ton has changed. Prior to 9/11 things moved at a snails pace. Many of the old wive's tales continued to be passed on and much of what was taught was just word of mouth. I describe it in class as the longest running game of "Telephone". The original intent was morphed in a bad way with changes in technology. After 9/11 a much more scientific approach was used. Technology changed, rifles, scopes, software, all that meant the old manuals had to be tossed away. You can buy those manuals on Amazon for $20 and if you look, you can download the entire manual for free. There is a reason they are given away or sold on Amazon cheap.
As an example, look at recoil management. It did not exist prior to Rifles Only and Sniper's Hide. We pushed that technique forward. Straight back behind the rifle, not off at an angle like when shooting with a sling. All recent developments.
DVDs are tough too, you'd need 10 discs in a series vs Streaming in order to cover the same material. 100 videos on YouTube would be a lot of money if you had to print them to DVDs. Really DVDs are dead in the water. So you only had a few short years to take advantage of DVD technology, not long enough when compared to Streaming videos. DVDs will always be a limited tool, mostly they were designed to get you interested enough to take a class. Why would I give away the keys to the kingdom, the idea is to attract and entice vs answer all the questions. Even here we say, "These lessons do not replace a competent instructor"... Consider we started the online training here on SH with Rifles Only in 2008 / 2009. Our classes were 110% full every month, we were traveling around teaching, the DVDs and Streaming lessons were just Icing and not the whole cake. Even now, I reach a ton of people giving lessons. Either in classes around the world, or private lessons locally.
When I go to the range, I film about 2 hours of video each trip. That gets edited down to 5 minutes, maybe I make two 5 minute videos from a single day, that means I have about 1 hour and 50 minutes worth of video that you guys never see. If I used that unseen video and put a voice over track on it, I could make a new video every single day. Sure the video would be you watching me shoot at a target, or turning a knob, or writing something down, but at the end of day, it would just be a highlight video with me talking over it. Great for content but bad for showing you something more than me shooting and hitting shit. I don't teach classes that way and I don't do my videos like that. Watching the little of Rex's videos I can get through, I would throw out 99% of what he shows. No trigger control, no follow through, just some Good / Bad Shooting. The world is full of Good / Bad Shooters, guys with no fundamentals who have adapted to hit shit. Not to mention, along with creative editing you can make anything look good. Ask Magpul... 36 takes on that 1 Mile stuff... Creative Editing is rampant.
Teaching Precision Rifle is not about me pointing out a target, you shooting it, and me spotting, then giving you the correction. Granted with enough reps' you can learn to hit anything. But for my classes, I do a minimum of a 4 hour powerpoint, for many of those classes the Power Point is 6 Hours long. I do a fundamental Eval, I watch you, write down everything you are doing wrong and then correct you. We drill, we test, we work to establish repeatable accuracy and precision at Long Range. Hell I can go down a line with 10 people and speak in Mils, MOA, giving each person a starting dope and correction without the aid of reference. Nothing is written down after the Power Point, it's all in my memory. As it should be this is my job, I get paid to teach precision rifle classes. One of the reason I don't give it away. ( MY PRICE IS WRONG)
If the videos get you interested in Long Range Shooting, that is all good. But to be perfectly frank, there is a lot more out there of a much higher quality. The lack of an actual precision rifle background is evident.
