I just started using my Giraud on .223 and the inside chamfer is uneven on all the brass, some cases are way off from one side compared to the opposite. I'm using once fired LC brass, I decapped, resized before trimming. Is it the brass or the trimmer? What do I need to do to fix this, I emailed Giraud but want to see what you guys say too.

Re: Giraud Uneven Chamfer Problem
You have to adjust the cutter in or out to trim even for the given caliber you are doing. Make an adjustment then trim the case. It may take a few pieces of brass before you get it right on.

Wouldn't that just adjust the trim length? It's chamfering unevenly. I did adjust the trim length and that is fine, just the chamfering is the problem. Where is the adjustment for what you are talking about?

Re: Giraud Uneven Chamfer Problem
I had the exact same problem and it was a bent decapping rod. Replace the rod and set it up high enough in the die so the neck is supported by the die as the expander ball is pulling through. That way the neck is concentric to the body and chamfer on the mouth will be even all the way around.
Let us know if this works.

Re: Giraud Uneven Chamfer Problem
You have to spin the case in the holder while it is cutting to get an even chamfer. Takes a little time to practice and get a technique down so the chamfer is "perfect".
Don't be afraid to call Doug Giraud or his wife Margret, they are great people to deal with.

Re: Giraud Uneven Chamfer Problem
It's ok if it is slightly uneven. It won't effect the bullet run out, since the neck is holding the bullet in place. The shell holder controls the length of the trim. On the cutter, there is a small allen wrench screw. Unscrew this and you can move the cutter in and out. You will need to move it very slightly one way. I use the piece of brass to help allign the cutter up. It just takes a few tries before you get it set just right.

Re: Giraud Uneven Chamfer Problem
Rotate the brass 90 degrees as the instructions note if that does not fix it you have the cutter head to close to the rotating centerline if the id of the brass is chamfered and the outside is not . it took a little while for me to change the calibers on mine

That had nothing to do with the problem as I was already rotating them 90 degrees. After I initially resized the brass I put them through a Dillon Super Swage for the crimped primer pockets, that bent the cases very slightly. Now the new cases that I had not trimmed are evenly chamfered by the Giraud and the cases that had an uneven chamfer were resized again then trimmed again and now have an even chamfer. The Super Swage stresses the case, you can adjust it but to remove the amount of crimp I needed it had to be done. I'll have to decap then swage and then resize on my next batch to prevent this (instead of decapping and resizing at the same time).

Re: Giraud Uneven Chamfer Problem
Someone was asking how the Super Swage does this, the rod the case rests on is much smaller than the diameter of the case and when you swage it the case has room to bend so instead of being straight it can bend like a banana, of course not visible to the naked eye but it did cause the uneven chamfer and I'm sure would have degraded accuracy.
Doing some more research on this someone had a similar problem with bent cases, he used a rod meant for a larger caliber on his .223 cases and had it turned to exactly match the inside diameter of the .223 cases preventing any room it could have to bend.

The problem was not that the inside and outside chamfer was uneven, I meant one side of the neck had more chamfer than the other side (all inside the neck). The 6 oclock would have a chamfer twice as wide as the 12 oclock for example.

Interesting. I get an occasional uneven chamfer, but I can't recall at what point I swaged the pockets. I may have to conduct an experiment.

At great risk, I'm assuming to "fit the neck?"

Yes it was to fit the neck perfectly so it could not flex.

Re: Giraud Uneven Chamfer Problem
Check the neck wall thickness. If it is not uniform, it will always vary. The case is held concentric by the od, but cut on the id.

Thanks Doug, I did check the neck thickness and that was fine. I called and spoke to your wife who suggested that. The Super Swage I was using must have bent them out of shape because as soon as I resized the brass and trimmed the chamfer was even. The brass that already had an uneven chamfer evened out again after resizing and trimming again.
