This is what I learned. 1. David Tubb is on a whole other level. 2. His system works. You really need the whole system. Rifle, cartridge, scope, mounted laser, and mounted chronograph. 3. In many ways his reticle system obsoletes a lot of systems. I was moving from target to targets from 350, to 800, back to 600, to 1200 and head shots were boring. 4. I can't make ammo as good as he makes, and to make ammo like his I would have to spend about 3 to 5 grand. If I were a serious shooter his 2 dollar ammo might be cheaper than making it myself in the long run. 5. The Tubb Adaptive rifle shoots like a dream . His brake is insane. His trigger is amazing. His new grip is amazing 6. The Tubb Adaptive Rifle, as a feat of practical engineering, is shocking how much better than all this other stuff. I know that will not make me popular saying that, but his rifle is not an improved Mauser. It's a whole other thing. Im sure there will be those that will have nothing nice to say, but that's only because they haven't seen it for themselves.
