When you where resizing did you have the handle camming over or did you stop when the die hit the shell holder. Set your die back up and resize a couple pieces that don't fit. Make sure you cam over and let the brass sit in the die a few seconds.

is the die touching the shellholder , at the top of the stroke , with a piece of brass being sized ? if the die gaps away from the shellholder any at all , you're not sizing to the dies full ability . what will cause this is , lack of lube .

if the die is staying in contact with the shellholder , I'm going to say it's a die problem .

No gap touches the shell holder. Very discouraged. Say i get a new die RCBS could this brass be saved?

I cam the handle as far as it will go sit for like 3 seconds. Ive done over 200 rounds of 30-06 and never encountered this problem.

Ok don't laugh because i've done it. Take a piece of paper get it to fit inside your shell holder. Put your case on top of the paper and size it. See if it chambers. If you have feeler gauges you could use them.

Have you resized brass with this die before in this rifle?
The other thing is the expander being pulled back thru the neck is also pulling up the shoulder ever slightly.
Try adding a little case lube to the inside of the neck before sizing.

I always lube the inside the case neck, i will try the paper technique as mentioned above and i will add additional lube to the neck and will see if that helps.It is a brand new die and i cleaned it with brake clean before use.

Added paper,extra lube and no change what so ever.

If you take some off the top of the shell holder the die will size down further. Another thing you might do is paint the case with a Sharpie and try to chamber it to see where the case rubs. Also measure the base of the case before and after sizing. If its the same the die is the problem.

while sizing a piece of brass , the press at the top of it's stroke , see if you can get a piece of paper between the shellholder and the die , or shine a flashlight and look for light shining through . if you can get a paper , or see light , get a different lube . it doesn't take much of a gap , a few thousandths will goof you up . I'm thinking the WSM brass takes a little effort to resize

also try these other guys suggestions and see what happens .

yes a correct die will size this brass . you have not ruined anything .

I could use some help. Only 20 out of like 110 brass i resized ended up being able to chamber in my rifle. I set the die lower and lower and lower and it did not change. What am I doing wrong? is it the die? Lee precision die and single stage press with Hornady unique case lube. I made sure not to use too much or too little. Pretty discouraged. I measured the brass that would chamber and there is no difference in overall length averages.

Honest Albertan, sometimes, chambers are out of round, or the bolt face isn't square to the chamber, or there may be other physical things with the rifle. I had a 300 WSM that I had to heavily resize with a small base die to get the bolt to close easily on the resized brass. It turned out that the bolt face wasn't square to the chamber. A spent cartridge would only go back into the chamber (and allow the bolt to close) IF I oriented the brass in the exact rotational position in which it was fired. Resizing wouldn't square the head of the brass with the side walls. I had to push the shoulder back about .006" with a small base die to overcome the case base being out of square. That was working the brass an adnormal amount. The manufacturer wouldn't repair the rifle, so I disposed it.

I would suggest that you take a cartridge case that had been fired in the rifle and (before sizing) reinsert it into the chamber and see if the bolt consistently closes easily. If not, there may be an issue with the physical geometry of the action.

Also, check to make sure the extractor is opening enough to go over the brass rim.

Luckily i had 1 cartridge i didnt size prior and it fits into the chamber great, easy bolt close.

Then most likely, there is something wrong with the die or the die set-up.
