I’ve been away from accurate bolt guns for a while. I see folks using Spiral Flutted barrels. Being schooled in civil engineering I canT believe some one would ruin a barrel like this. A straight flutted barrelbis similar to an I-beam. Very strong, stiff and lightweight for diameter. A spiral flutted barrel is nothing more than a twisted i-beam. Extremely weak with very poor longitudinal stiffness. Exactly what you don’t want a rifle barrel to be. This is why building collapse during large fires when I-beams twist and fail.

might look cool, but it is a very poor design for a rifle barrel.
