Hello,
I have a problem, can you help me?
with new barrels, after fireforming/break in I have to push down the shoulder of the brass about .008 inc. to close the the bolt in a correct way.
I am using to chambering (Bartlein GT) the Tony Boyer 3 (PTG) and to make the die the resizer Tony Boyer 3 (PTG) and the GO and NOGO is ok.
I did not understand why I have to push down the shoulder too much and the result is a disaster (no ignition and all flyer)
Thank you in advance for your help
 
Yes goodgrouper, I tried the chambering with 2 different pair of GO/NOGO.......and the result is OK.
 
My gunsmith told me that he used a resizer reamer to make my die, is possible to control if the problem is this? I have only an another dies and is a redding small base 6ppc...
 
If I understand the problem correctly "goodgrouper" has hit your problem. You are having to screw your sizing die down far enough to shove the shoulder back 0.008" and having failures to fire, it's likely that your sizing die is too large in diameter. By the time you've got it screwed down far enough to get the diameter small enough the shoulder has been pushed back too far. If the gunsmith did indeed use a resizer reamer to cut the FL die for you it may be that the reamer is too large.

Give the Redding small base die a try and see what happens. If it works it might be time to talk to the gunsmith if he lives close by. Or send fired cases sized with his die, the Redding die, and unsized, and explain it to him. If he's a reputable guy he should be interested in making the problem right. Explain it all politely and present the evidence of the cases.
 
Yes, Ita, go read what we said to answer your question in the Gunsmith Forum.

The minute you said "Boyer 3", I was pretty sure what your problem is......jackie

The Harrell #3 die usually fixes this problem, but, the best solution is a custom f/l die. Either the Harrels, Jim Carstenson or any of the other custom die makers can fix your problem if you will just send them a few fired cases.

You are having to set the shoulder back now 0.008" to get down to the smaller part of the sizing die which means the chamber and the die do not match. This will greatly shorten your case life and creates a potentially dangerous situation.
