For the first time in my life I don't want donuts! LOL
Move the bullet forward about .020 on #2 and you will probably be out of the potential donut area which can occur at the neck shoulder junction especially on necked up cases.
I made a 7x47 by necking up a 6.5x47. After firing a few rounds, I noticed a definite bump when I was seating a bullet. I wanted to turn the necks anyway, so I made a special effort on the neck-shoulder junction. It helped some, but not completely. Fortunately, I had a 6.5 neck reamer, and I ran that in with only light resistance until I came to the shoulder. Then, I cut a lot of brass from the inside of the neck.Its alot more common on necked up stuff because you transition some of the shoulder to part of the neck.
I have never experienced it necking down
I wouldn't worry about donuts. I've been hearing about them for years. Hundreds of rounds later, some with boattail well below the junction, I've never had a single donut form in cases loaded several times.For the first time in my life I don't want donuts! LOL
One doesn't worry about them, one manages them. They can be reamed or avoided.I wouldn't worry about donuts. I've been hearing about them for years. Hundreds of rounds later, some with boattail well below the junction, I've never had a single donut form in cases loaded several times.
