[QUOTE="pyroducksx3, post: 553934, member: 20443"] I dont necessarily agree that the belted cases are less accurate. Some of the complaints about them are that it is difficult to truely full length resize them, this can be done with special dies though. Also the spacing of the belt can change with different brands or lots of brass. Most people transfer the spacing to the shoulder after firing so thats not really a problem either. As far as saying that the purpose of the new ultra mags is to push the velocity limits for bragging rights, I dont think is really accurate either. The 30-378 weatherby is pretty close to the 300 RUM and the 338-378 weatherby actually has more velocity potential the the 338 RUM. These new cases are just effiecent and a good option for people looking to shoot long range. If 600 yards is your goal you would be better suited with a lesser chambering like 7 rem mag or 300 win mag. When you are pushing limits way out there you want velocity which equals energy these new magnums provide that. Also at extreme distance the benifit of having the extra velocity cuts down your margin for error. if you have a rifle that is shooting 200 fps faster you will have a better ballistic profile. This allows you to have a better margin of error, such as not reading the wind just right [/QUOTE]
