gknives,
First, please describe the process you used to determine that the headspace was 'perfect'. Also describe your technique of tightening the barrel onto the receiver. Be sure to tell us what the bolt looked like.
Second, there are various opinions about the shoulder/inner ring contact. Most gunsmiths working with Mauser M98-type rifles strive to rebarrel with contact on both rings simultaneously.
Mauser produced somewhere in the neighborhood of 13 million M98 rifles. The length of the thread tenon and the depth to the inner ring were both controlled with reasonable accuracy. Occasionally though we do find a very slight lack of contact between the barrel shoulder and the front ring or the rear of the tenon and the inner ring. 'Very slight' can be interpreted as just a couple of thousandths of an inch.
An 1/8" (0.125") is a tad more than any of us would allow. It's sloppy and lazy at the very least. Your tenon needs to be shortened then have the chamber cut for proper headspace.

I believe that your problem might be caused by the difference in action/receiver specs. The Yugo 24/47 rifle isn't a true Mauser 98 that the Herters barrel is spected for. They were originality made in Belgium in the 1920's for the Yugo army on a intermediate length action, not a conventional standard Mauser 98 as made in Germany.
EDIT #1, Get hold of a copy of Frank de Haas's book on bolt action rifles. In the back it has a reference section that has sketch's, they show the difference between Yugo Model 24's and standard Mauser Model 98 barrel shanks.0 -
as stated the model 24 is an intermediate action. however, your problem is that this action had the end of the barrel releived for the extractor. unlike the 98 0 -
When sizing a barrel for correct fit, and you have to deal with 'bottoming force' on the assembled barrel/receiver, would either the barrel shoulder, or the inner receiver ring have bearing preference?
Or, do you have to strive to get the setup so exact that both the barrel shoulder, and the receiver's inner ring both receive equal (50-50) bearing (torque) loads simultaneously?
Or, looking at this inversly, should the shoulder, say receive 70pct of the load, and the inner ring 30pct? Or visa-versa?
Thanks. I hope I'm not intruding on this string, as I assume (you all know about the word ASSume), the OP would like to know as much as he can. Joe0 -
Jeez, you guys take all the fun out of trying walk someone through the process of discovery!
Yes, it's a non-standard M98 Mauser extractor/bolt nose and the tenon needs to be machined.
Mauser made 4 action sizes as documented:
Short (Kurz)
Intermediate
Standard
Magnum
All of the actions used for military bolt action rifles were intermediate (with rare exceptions) because they were chambered for intermediate length cartridges such as the 7.92 x 57 Mauser and a host of others. This is right up there with the argument about thumb cuts...
The standard or long action was available in sporter rifles (made for the British primarily) and then later when FN designed the new improved M98 version with a solid side. These were made for the '06 length cartridges for the most part. I write this only because there are rare exceptions to everything written about Mausers. We won't get into round actions or single shot Match rifles.

thank every one for your input.i stripped the bolt then tighten as tigth as i could with a wheeler action wrench did not use a cheater bar but the barrel was tight.used go gauge ,ok then no go ,no go.. test fired today brass looks good. 0
