[QUOTE="J E Custom, post: 1370822, member: 2736"] I agree with everything but the pressure difference and velocity in the long throated than the against the lands set up. A good example is in the big Weatherbys that have lots of freebore. If you build a Weatherby and short throat the chamber, you will not be able to use Factory ammo without over pressure issues. Most of the time they will blow the primer. and with loads within pressures, lots of velocity loss will be seen. (The main reason for the big Weatherby cartridges. The long throats are the main reason that the velocities reached with them are considerable higher than norm. The ability to load more powder without increasing the pressure is the main reason I like freebore. The 338 Texan is a good example based on the same case as the 338 Edge (300 ,375 RUM) the velocity with 65'000 Psi and a 300 grain bullet exceeded 3150 ft/sec. Here is a Post by a really good friend about the cartridges performance.
