Sorry. I don't reveal how I bed or chamber barrels. I have modified some techniques over the years and the results have spoken for themselves, Piercision Rifles - Results The results page would be a little longer but I turn away majority of fclass and benchrest rifle builds people ask me to do. This is due to I have a big demand for hunting rifles and I can do them in half the time as a fclass rifle. I also have several shooters on the national teams who won't let anybody but me do their work for them.
