You will find that the majority of shooters who frequent this site use one of the readilly available Custom Actions as a basis for a Rifle that is to be used in some type of extreme accuracy discipline. That is what the level of accuracy demands.
Even many fine Hunting Rifles are now based on a Custom, such as The Lazerroni, Time Precision, McMillian, Dakota and others.
Of the "Factory" actions you listed, the Remington 700 and the 40X are by far the easiest to upgrade to the type of tolerances that a good Rifle Action demands. That being, machined surfaces that are all truely straight with each other,and in alignment with the bolt way. That is why they have been by far the most popular choice of shooters who want to build a custom Rifle on a Factory Action. Sure,the Remingtons are atrocious out of the box, but Gunsmiths have made good money for years "getting them right", because they are quite easy to work on.
All you have to do is look at most Custom Actions, and you will see that they are, in reality, improvements on the basic Remington design. Even the Panda and Viper, which at first glance look entirely different, share many of those basic design features.
Most of the others you listed have some sort of "quirk" that makes them too much of a hassle to fool with, that is, when compared to the Remington. But, going under the assumption that you can do anything, if time, and money allows, I suppose each of the others have some sort of following. .......jackie
