[QUOTE="Kmccord, post: 1585046, member: 99039"] Donuts occur from over sizing the case, pushing the neck down during FL sizing. To correct this would require purchasing a inside neck reamer, once the donut has been removed, I would look at only FL sizing about .002, enough to close the bolt, this will aid in not creating a donut by pushing to much brass down on the neck junction. Some custom rifles are throated to where the bullet will not seat into this junction, thus eliminating the worries with donuts. What these can cause is high ES and SD, once you eliminate the donut, my next step would be to just bump the shoulder down about .002 in your FL die, once the case is corrected, next would be looking at your reloading steps, specifically powder measurements. I use two scales, one is my electronic scale for powder dispensing and a balance beam scale to verify correct grain load. I will use a powder trickle to bring it up to correct load. My next step is verifying each load is the same OAL, I use a Hornady OAL tool on my calipers to measure to the Ogive on the bullet, versus measuring to the tip. Once all is set the same and your barrel is clean, if the group doesn't close, then may need to look at another bullet to try. [/QUOTE]
