[QUOTE="VinceMule, post: 2904181, member: 122164"] Years ago, I made a lot of 7 STW from 8 Rem mag cases, accuracy was sub 1/2" at 100 fire forming, I do not remember any doughnuts. Reamer we had ground was for 120 and 140g Nosler Solid Base, 3850 fps and 3650 respectively, 27" Hart 9" twists, #5 contours. I prefer to neck turn the parent case, then neck down. Then part of what you turned becomes part of the shoulder, mitigating brass migration. [/QUOTE]
