Martin AKL, from Boise,
Thanks so very much very this very explicit email, which is absolutely special in terms of accurate information. A bolt will be ordered, and since that 28 inch heavy barrel can't be factory, pulling it off and setting the proper headspace should be pretty straightforward.
This site is really special to me, and recently I had a rifle which was totally frustrating to deal with in terms of accuracy to be rebarreled in a 6.5 Sherman chambering, with a reamer supplied by Richard Sherman of Idaho. That 6.5 Sherman, which has ballistics equal, according to my chronograph, to a .264 Winchester mag, performs incredibly well. The first two sight in shots allowed me to be on target and the next three went into .266, so after two frustrating years, the gunsmith here who did this job for me, will also be headspacing this .240 Weatherby for this friend.
Thank you so very much at this time.
Gene S.
