While I agree with what you're saying about how the smoothness of an action does not make it any more accurate, I have to say that a smooth action is a whole lot nicer to have than one that tends to bind up if ran really hard. For instance, I have owned several custom actions and know that between the TL3 and a 737/NBK.. the Impact actions are a lot less finnicky when it comes to running the bolt hard. Now the TL3 is smooth, but you have to learn how it likes to be ran, and once you do it's a fantastic action with a ton of great features. The only thing is that if you're in a situation where you get super excited or under a lot of pressure to get a second shot off quickly, the Impact actions simply do not care and are practically immune to any type of binding, while the TL3 has a tendency to hang up unless you put downward pressure on the bolt handle.. I know if you train enough, you should not have any problems with any action you go with.. but I have to disagree that there are no positives to owning the "smoothest" action available. (Just my opinion)
