I talked with Jack Huntington and he explained it and I informed him of my intent to purchase a BFR 475 Linebaugh/480 Ruger with a 6.5 inch barrel. He knew of the epoxy method used by BFR to retain the ERH. And he offered to share the deadman stud application method to take shear forces off the screw and retain the ERH with BFR. I called BFR and spoke to Brett who did not know of that method but was glad to hear about it. Their BFR 500 Linebaugh has been known to loosen their ERH even using the epoxy method. I do not want an epoxy method to keep my BFR from loosing its ERH. If and when I get a Bisley model BFR I will ask for the use of the deadman method to keep the ERH intact.
Jack Huntington said the 500 Maximum was really tough on ERH and two or three deadman studs were warranted to be used with that one.
