On the 7 mm WSM, wasn’t there something in a flaw in the design of the case from Winchester in that the 7 mm WSM could be loaded into a 270 WSM or vise versa and that’s why they had a delay on the production of rifles and ammo? Winchester had to redesign the case to eliminate this problem and that’s why the 7 mm WSM market has been playing catch up ever since then !!!
