| 1. Is it a F/L die set up according to the instructions that came with it? 2. New brass or once fired? 3. If 1x, was it fired in your rifle? 4. Never mind about the crimp.

| 1. Yes, a full length die set up using the instructions that came with it.
2. New brass (Winchester). I noticed that the mouth on these was anything but uniform, so I did run them through the F/L resizer.
3. N/A.
4. If I were to be using a .30-06 BAR would that make a difference regarding the crimp issue? |

| Well, it's new brass, but I did measure several to be sure.
I also worked some unprimed brass through the action, and that works fine, so I don't think it's the neck that is causing the pressure. |

| you are probab;y stretchin the brass as the expander is pulled from the brass. lube the inside of the neck and resize a couple. chamber them, feel for resistnce as you close the bolt. adjust the die in a little at a time untill you can not feel any resistance. |

| I did ... unprimed, unsized brass cycles fine. The neck doesn't get in the way at all. |

| Problem solved.
I had failed to remove the case lube after sizing. Rookie mistake. Things cycle fine now. |

| Be sure and swab your chamber out with a patch soaked in brake cleaner.

| I always full size new brass in any caliber. New brass is not to exact spec as it has tolerances and manufacturing variable that affect shoulder & neck dimensions. If you compare a full sized new brass with an unsized one, you will see the distinct differences in the shoulder & neck areas. I always trim & weigh new brass after sizing to establish uniform lots. I would also recommend that you try H4350 powder - it will give you more uniform velocities under different temperatures.

I'm a little surprised this would happen unless you were picking up some grit or powder clinging.  although you have solved the problem I forgot to point out another potential candidate. Swelling or buldging at the shoulder body junction caused by your seating die being too far down and the crimping portion pushes down on the neck. roger
