Whitworth,
Jack Huntington related the ERH loosening on 500 Maximum revolvers he had experience with. And Brett at BFR Magnum Research informed me that they had not had a perfect solution using epoxy to keep the 500 S&W magnum ERH from becoming loosened. I do not believe Brett was inferring a rash of ERH failures.I feel that Brett wants perfect performance and even a few or even only ONE incident is TOO MUCH and gets his attention. Just what I sensed and picked-up from the two conversations I had yesterday with Jack Huntington and Brett at Magnum Research.
