[QUOTE="Hugnot, post: 2340024, member: 115658"] Just my point ! - there is no load data for the .300 WM having COAL greater than 3.4 inches. The .300 WM has been handicapped since its inception due to insistence that the round fit into a standard .30-06 length magazine requiring bullets be deeply seated into the case thus restricting powder capacity. Loading a extended length .300 WM to equal pressures of the .300 WBY will reduce velocity differences to 2-3% between the two. SAAMI data: [ATTACH type="full" alt="Screenshot (285).png"]312190[/ATTACH] [ATTACH type="full" alt="Screenshot (284).png"]312191[/ATTACH] Not much difference between both and this is with the shorty, powder capacity challenged 3.34 COAL .300 WM when loaded to SAAMI specs. [ATTACH type="full" alt="IMG_1594.JPG"]312201[/ATTACH] I think .30's have a place in long range shooting - recoil, but 200 grain plus .308 bullets hit harder than 6.5's. Should I plan to get another .300 WM, I would look for a used Rem 700, magnum bolt face, long action, and build it into a single shot having a light Palma contour, 28 inch, 9 or 10 twist, stainless barrel. Might use cheap aluminum ADL trigger guard. It would be chambered to accept the above - 208 grain bullet. Cost comparisons between the two easily favor the .300 WM.
