[QUOTE="Barrelnut, post: 1638527, member: 74902"] Yes, I happens more with sharp angled shoulders, like a WSM cartridge that has a 35% shoulder, I believe. Just the thickness of the brass can affect whether it doughnuts or not. I have had doughnut issues with Norma that I don't experience with Winchester at all. The more you push the shoulder back and the angle at the necks causes the brass that is pushed forward by resizing the case to pile up in the sharp angle at the shoulder neck junction. Think the 270 case is just 20% so not sure how quickly it would doughnut. This is the kind of issue that a doughnut can cause, if you are seating the boat-tail of the bullet below the shoulder neck junction. You can use a paper clip with a small sharp tip and run it down the neck at the shoulder neck junction. You can usually feel the doughnut. Might be able to see it with just a bright light. [/QUOTE]
