I was trying to full-length size .378 Weatherby brass down to .338 for my .338 A-square and noticed the radius at the junction of the neck to shoulder was a tad too sharp, shaving off a little brass instead of nicely pressing it down to the shoulder. Called CH4D and Beth (the nice lady who answers the phone), immediately recognized me and even remembered me ordering the dies! When I told her what was happening she just told me to send the die back along with a case so they could see what I was talking about and they'd handle it.
I love a manufacturer standing behind their product. I bet the die will come back so well hand finished it'll look like a piece of art.
