[QUOTE="Dollarhyde, post: 1954062, member: 21784"] It's a no-belt no double-radius shoulder solution for guys that want to run 257 WBY speeds but want more ideal brass geometry. This link shows the initial COAL, BTO, and other considerations in the early stages of the project. Reamers will arrive in September and dies will be machined and shipped as soon as the reamers arrive.
