[QUOTE="velocity-is-key, post: 503879, member: 32874"] Thank you JE that sounds like a sensible solution that I will try and I guess one could in all practical procedures "taylor" the curve by varying this "freebore" and recording the results which I am sure you have done to get the staggering velocity from the big weatherby. My neck is a average .276" and my loaded rounds are a .274" with a unloaded neck of .273" after the brass is cleaned up all the way..With my bushing dies I really don't need to neck size as after the brass spings back its pretty dare close to .273 again.. I typically have gotten 15 reloads on the same brass with annealing if I feel a increase in seat tension... I am betting that those performance figures for the big Weatherby were also had using a aftermarket barrel rather that the factory hammer forged setup, but never the less it does make me want to design another gun off that cartridge even if I have a perminent neck problem after all that research I did years ago with the factory set up minus the muzzle brake... Thank you again for any and all input... velocity [/QUOTE]
