[QUOTE="Mikecr, post: 1634775, member: 1521"] Donuts are inherent to manufacture as the brass is thickest at webs & thinning all the way to mouths. All new brass has donut area near neck-shoulder junction. It's just a matter of us making this an issue or not. Dount area(the point of problem) is avoided by not seating bullet bearing into it. Hot loads, causing excess up-sizing, does not amplify donuts in itself (unless forming to higher cal), but the downsizing of that rolls thicker body brass towards thinner necks, building donut thickness. You can press this outward with a mandrel provided chamber clearance for it. That's hard going and can collapse shoulders. Best handled through neck turning of new brass, onto neck-shoulder junction. Reaming is a last resort & often horrible in results. I'd get the barrel throated for longer intended bullets. [/QUOTE]
