Mr. T - there's no problem with the delrin. Using some type of bearing just costs more and doesn't do any better.
Again - there is no problem with delrin slides on a rail gun.
To answer your question concerning wear, it doesn't matter. Ten shots plus sighters won't make much difference.
Thanks for the clarification , its my first rail build and considering that i am in Europe , there are very few rails around here so i have no posibility of seeing one live that is why all the stupid questions.
