Harrell's 6 dasher die

[Alex Wheeler]

Good afternoon,
I have been having a problem with this die fitting my chamber. The die is great, but I have found the shoulder angle to be different than my chamber's. How I found this, Sinclair makes two comparators for the 40 degree cases. One is meant for the smaller calibers and the other for the larger ones. If I use the correct comparator that hits the shoulder at the datum point I have to bump 3-4 thou for the case to chamber how I like. Now today I tried the lager comparator. It hits the shoulder near the shoulder/body junction. I found that if I measured here I could bump .0005 and get a smooth bolt. Now that same case will show a .003 bump at the datum but only .0005 at the shoulder junction. Holding two cases together by the necks, A sized case has a visibly different shoulder angle. The best I can measure it is 2 degrees. I don't have a way to precisely measure the angles, so I don't know what is out of spec. Any one else seen this? Two degrees is a lot. Could this be spring back of the shoulder?

The Sinclare Tool is generic and meant to fit anything with a 40" shoulder. Why don't you use the brass bump measuring tool that came with the Harrell die and is made to fit your cases? I have four different Harrell dies and all fit perfectly. If you do find it's a die problem, I'm sure the Harrell's will correct it as they are good honest people. But for the life of me I can't figure how they would get the shoulder angle wrong when the die is made to size the cases fired from your actual chamber. Keep us posted, I'll be curious to hear what you find.

Thanks for the reply. Harrell's doesn't actually make the die from your brass. They pick a die from stock that closely matches your fired brass. I don't think it is the die, but yes, Harrell's is great to deal with and would deffinately make it right. As far as the tool they send, it only hit the case shoulder at the body juntion, and gave false reading on my brass. I took a cast of my die, Best I can measure the combined angle is 80 degrees. So now I'm more confused.

If you actually have 80" and I have no reason to doubt you since you took a cast and appear to have a handle on exactly how Harrell's makes their dies, (you are correct about getting one close from stock and then fitting as close as possible to sent cases). I do believe a phone call may be in order. Keep us posted with your progress, hope you get it ironed out.............Chuckhunter

If you sent down three fired cases like they ask that were fired at least 3 times the die should work. if not call them and tell them what is wrong. send the fired cases along . Don't size with the die if your having problems with....jim
