When I spoke with Krieger about fluting a barrel they said if THEY did it then it would be warrantied but if someone else did it then the warranty would be void. I think it has to do with stress induced into the barrel during the fluting process. I believe the fluting needs to be done prior to the final annealing and the final polishing of the bore, during the contouring phase to insure consistant bore size from end to end.
