You are correct. The only time that "dead on tracking" is a concern with a Rail Gun is if one of your buddies happens to look through the scope and move the top back and forth. If it by chance happens to track dead on, you can give him the old speech about the hours you spent getting it that way.
Aside from that, as long as you remember to place it against the stop for each shot, it is of little consequence.
When stockers say that the action is dead in alignment, how true is that. Since some ID's of barrels can be somewhat in miss-alignment with the OD, whats the point.
And then there are the Gunsmiths who align just the first few inches of the barrel for chambering, and leave the muzzle to do what ever it is going to do. Heck, that barrel sure isn't in "alignment with the stock".
A shooter at Rachels Glenn ask me this week end why his Rifle did't return to exactly the same spot every time after each shot, or even if he moved it back and forth witout shooting. I told him I didn't have a clue, because mine didn't either, and it didn't seem to make any difference at the endof the day.........jackie.
