The bolt handle is the work of my late lamented gunsmith friend and partner, Harry Creighton, who was a real artist in altering bolts. His Mausers, Enfields and Springfields bear a more than casual resemblance to pre-64 Model 70 Winchesters. I know of no one presently who does them as well.

Cartridge case length and over all length are the same as the .300 Winchester Magnum, 2.620" and 3.340", although the fired cases I measured were all but one over the 2.620" trim to length. A .416 bullet slides easily into the mouth of a fired case, so there seems to be no "dreaded doughnut" where the original neck was expanded. I can't remember for sure, but I believe there was no special reamer used to chamber the rifle. I believe we just used the .300 Winchester Magnum reamer with a .408" pilot to form the chamber body and then used a neck and throat reamer to cut the rest.
