6XC-how to remove donuts (I hate to even bring it up but need some help)

[savagedasher]

The only way I know to remove them is with a reamer. Larry

My brass is Norma 6XC only fired in this chamber. However, the chamber seems a little odd as it has a very short throat.

Make sure your throat is carbon Free, finding your BTO should be easy knowing the only thing stopping the bullet from hitting the lands (only) is the lands, Chamber a long seated bullet, Make sure it passes the concentricity test before you chamber it (its got to be concentric) then inspect the bullet (Magnifying lens) for scratches and land contact. If you need more throat. Do it. If you need donuts out, ream them out. If you need more help PM me.

I get donuts in the Norma 6XC brass that I use. I neck turn the shoulder/neck junction to remove them. Regards JCS

I have had great results with running a case into the die. Take die and chuck up in my lathe and bore out just the donut. Down side is you need a lathe. Lol.

The problem with the inside reamer (as Matt will tell you) is it scratch the inside of the neck and that can affect "neck tension" and all the consequences..... When the OP said "it will do the job...", sure it will remove the donut, but.....

I use a mandrel with 600 grit psa after INR, seems to smooth out the INR Marks I think

You do understand that the man who designed the 6XC is the one who posted #15? You might want to follow his advice.

Rifleman700, I know who he is. I shot with him once at Perry. But he did not build the rifle as far as I know.

Just an update, I did try the inside neck reamer and shot a Palma match today. 39g H4350 with a 105 Berger Hybrid jumping 10 thousands. It shot fine with a 448-22x. The two 9s I shot were all me. Not much wind today so it was a good day to work on my position and fundamentals. The reaming did not seem to effect accuracy on a bigprone/sling target.
