You guys all sound confident using hand held drills and dremels turning screw heads and backward bullets into a rifle crown, but it makes me cringe. I cannot see how anyone can place an even crown on a barrel, regardless the degree, w/out using precision equipment.

All you are doing is removing a
very small amount off the edge of the rifling at the end of the bbl, giving it a new crown.
I was scepical, but have ahd good results a couple of times doing it.
