A Pappas rest will point a rf as well and quicker than a rail gun.
The only advantage to a rail gun would be stability. I couldn't imagine a rifle in any rest being as stable as a rail gun.

Have you shot off a Pappas one-piece rest..?? If not, you neede to try it before you make that statement.. They are very stable...

There were a few 22 rail guns brought to a few matches several years ago. They got beaten so handily that the owners quit dragging all that weight to the line.. With even 7.5 pound sporter rifles needing a 250 with high X count to place, why drag 40 pounds around.
If they would allow unlimited scope power on sporters, many of us would not even own a 10 1/2 pound rifle.

The problem with the rail setuos I have seen is that they are designed for CF group shooting don't have enough sight adjustment to cover the whole RF target without moving it sometime during the match. If that problem were addressed, I'd think they would be very good in RF score matches. You would need to tune for the ammo but you couldn't get a better more cosistent hold.
I had one shooter, that said he was developing a special rest, so all he had to do is make one click per shot, and he would take out the dot every time. Just think, 2500 every target. Strange, that he has never showed up at a match to show off his fantastic machining skill.
