I think this was probably done by the fingers in a lee die. And i never seen anything like it either. Im sure a regular sizer or seater will not do this.
Varmint al has some great tips on using steel wool to smooth out and ridges left by cutters.

This is why you ALWAYS outside chamfer first and then do your inside chamfer second. about any load manual printed in the last 50 years mentions this. Pretty basic stuff.

I needed this article! I have had trouble with my 6.5 BPC cases shaving bullets from the start. (though less severely and more evenly than shown.) I too use a screwdriver and do the outside last! I recently started using the deeper/larger part of the Lyman M-die to open the mouth a bit more. it seems to fix the shaving but I am getting uneven tension (I can feel it now.) I need a bushing die but I might have to settle for a new chamfer right now. (It shouldn’t take too long to get the bucks for a FLbushing die from C&H though.) Thanks!

I have never seen a neck so damaged in my life. I am sure this was overdone to prove a point, but if this is a common event in your reloading procedure, you might consider getting glasses and taking a valium.

I’ve been happy with the RCBS 3-way cutter for the inside chamfer, outside chamfer and trim all in one motion type thing for awhile. Maybe there is some thing to it after all and it’s not just some gimick.

I discovered the importance of “gently” using a VLD rebutting tool when working with moly coated bullets. Almost no matter what you did with a 45 degree debarring tool, the moly coating was damaged. The seating force required when using a VLD rebuffing tool is almost always less.

Chucking one of the hand held VLD tools in a drill is quick and gives a much better “feel” than doing them by hand in my experience.

Even where there is no obvious visible damage to the bullet, one has to be suspicious of damage to the core when the seating pressure is great.

I’ve been using the K&M inside taper neck reamer for years, turning by hand, or with the cutter shaft mounted to my Forster case trimmer, and I’ve never experienced anything like the pictured cases. I take a very light outside cut with the “rocket ship” de-burring tool, followed by another light inside cut with the K&M to the recommended depth of 1/32″. Flat-base bullets start into the case mouth without any undue pressure required, and certainly without the extreme damage as shown. Maybe the pictured results are one of the reasons I never use any type of a power tool. Works for me.
