[QUOTE="Trickymissfit, post: 523788, member: 25383"] lately I've kinda gotten on the 35 degree bandwagon with large diameter cases, but they still don't run thru a forming die all that well. Also looking back and doing some serious thinking about it; I don't know if the 40 degree shoulder angle is the main reason for the doughnut problems, but I do think it sorta amplifies the situation. Reason I say this is when I look at Weatherby mag cases, I don't see it much. They will run anywhere from 44 degrees to nearly 48 degrees when CAD'd out. I kinda have the feeling in the back of my head that it's the sharp shoulder with the small radius at the neck and case body stopping the flow of brass right at the weakest point. what do you think? gary [/QUOTE]
