[QUOTE="yobuck, post: 2809006, member: 12443"] Remember that the velocity numbers will be affected by the location based upon the altitude. Also remember that the larger cases will require large diameter custom dies and a larger loading press to handle them. 378 Wetherby cases can be loaded on a standard size press. A 338x378 will send a 300 gr bullet to a velocity of 2950 or more in elevations of 1000 ft above sea level. A standard 416 Rigby case will send the same bullet a bit faster, and the improved version faster yet, again with standard loading tools. My 338 Big Baer with a 34” barrel will send a 300 gr bullet 250 fps faster than my sons 338x378 with a 30” barrel. But i use 30 more grains of powder in order to do it. Plus higher brass cost and a whole nuther loading outfit to load. You know what? its not worth it, if i had my time to do over i would have used the improved 416 case or the 378 Wetherby case. Thing is you have to try them all at the same place on the same day, and we have with the 338 Edge, the standard 338 Lapua, the standard 338x378, and the 338 Big Baer, all with 300 gr bullets.
