[QUOTE="Darryl Cassel, post: 21187, member: 34"] Brent There is no belt on the 416 Case. When using extremely hot loads, the web area will expand just like a case with a belt does. The die (Like most dies)does not come down far enough over the bottom sides of any case to reduce this expansion. With the expansion it also causes the primer pocket to expand which I can fix, that's not the problem. The problem is the web expansion, it makes for hard extraction and entrance of the case into the chamber. This also happened to the 378 Weatherby case when I used the 338/378 and the 30/378 and hot loads. With the 300 gr, I have found that if I reduced my speed by 100 to 150 FPS I could add much more life to the brass and with the high BC of the bullet, you don't need the speed I originally thought I did. Later DC [/QUOTE]
