The action is more ridged due to the amount of material that is retained in the machining process. The standard actions have about 70% of the material removed between the front and rear of the action. The target action also comes with a trigger that can be adjusted safely to a lower setting than the standard Accutrigger. It is possible to shoot and compete in F/TR with a standard action and a quality stock. Trust me on that. So unless you just have to go all out. Get build yourself a rifle and go have fun. You will find that your personal form and reloading abilities are much more important than the brand of action you use. well unless you want to shoot 600 with 60x's.
