Case bulge just ahead of the web area

You should be warned of a dire consequences of using Lapua Brass.
If they make brass for your Rifle, you will never use any other brand again.....jackie
 
How do I choose a bushing when I order, for brass I don't have yet? Or should I just order the brass and order the bushing later?
 
The other part of the problem is the lack of fit between the die and chamber. You can have someone polish out the body of your die, or have Hornady make you a custom one from fired brass. Either will reduce the sizing force required, and create a better fit in the chamber. Even good brass doesn't respond well to a large chamber in combination with a small die.

Boyd,

Could he use the same reamer that cut the chamber to make a die?

Thinking this through, you are correct, the relationship problem, is between the die and chamber. So, what brass he uses is irrelavent, until he gets a different die or modifies it.
 
my take on the brass

from the pictures it appears to me to be insipient head separation. if one took a piece of wire and dragged it on the inside of the case they would be able to feel a valley where the bulge line appears on the outside of the case. this is a headspace issue. when forming brass for cartridges like the gibbs line one has to make the bullet touch the rifling to keep the heads from blowing off the brass while forming. just my opinion, Greg Moyer

Boyd, that's an excellent point and one I neglected to include in my responses. The Redding people are very good about furnishing the internal dimensions of their various dies...a phone call to them would be the way to start. I've messed with a couple of situations like this before and in several cases a neck sizing die for the particular chambering gave just enough case sizing to effectively act like a full length die in a 'big' chamber.

Just a thought. -Al
 
I spoke to Melvin at NULA when I found this problem and Melvin told me his chambers are cut with the same reamers that Redding uses for the dies and I am to adjust the die to touch the shellholder and not to back it off. The rifle is going back to NULA on Monday for a different issue and he is going to check the chamber just to be sure. I am going to include fired brass. I may have overexagerated about the difficulty of sizing the brass. It doesn't seem to size any harder than any other cases (various calibers) I try to FL size. Since I neck size everything, I am so used to the neck sizing operation to be so easy that I forgot just how much difference in resistance there is.

You've convinced me of that.

I came across some brass that was fired in my brother-in-laws 30/06. It too has some bulging in the exact same spot as mine.
An empty,fired factory R-P case measures .469" at the bulge spot and .464" just ahead of the extractor groove.
