I am not sure what your talking about 1st there are many people like my self who shoot off a bench all the time. I use sand bags not a cradle or vise as you refer to. I do this for accuracy, testing loads, sighting in rifles, etc. Most every one at our club does this for what ever reason they have. I do this 3 or 4 times a week always to try to find the best load for a given rifle.
There are many who use bipods etc with there ARs etc for what ever reaso they have most for accuracy testing and sight in.
I am not qualifed to speak about shooters who shoot bench rest rifles, what they use or the equipment they have. However I do know one reason they do this it is to strive to shoot the perfect group which if I am correct has been done very few times. I know one guy who quite benchrest shooting for several years, he told me it was drining him crazy and he had to get away from it. He is back at it again with a better attitude and once again enjoying the sport of shooting.
If you ever have a problem loading find a benchrest shooter from my experience most of them have forgot more about loading then I will ever know.
IMO there are 3 classes of reloading
1 the reloader one who just refills cases to go shoot more
2 the hand loader who strives to get the most accuracy out of each rifle
3 benchrest loaders
