[QUOTE="BoatTail, post: 2328288, member: 74670"] I'll cover my experience breaking in the barrel on the 6.5/300 WSM later in the thread. It was not good. Neck, and Lead dimensions as well as forcing cone angle are shown here. [ATTACH type="full" width="372px"]308765[/ATTACH] The dimension for the throat is 2.569" from the case base. By the way, I often get mixed up on the proper terms and perhaps you all can help. I have used Freebore (FB) and throat interchangeably to specify the distance from the case to the point in the chamber, after the case, where it begins to taper. I now know it is wrong. In this drawing I would have said the 0.220" dimension was the freeboard, or is it the 0.237' dimension? Help me use the proper terms for each of these two dimensions (0.220 vs 0.237). [/QUOTE]
