Everyone knows the story now and all is well, my mother is very used to this behavior when it comes to buying guns, and my now wife wasnt surprised in that gun buying behavior either lol

I reference Nathan’s database whenever I am contemplating a new caliber. His information is always factual and unbiased which is very refreshing in this day and age.

Read most of the article. There are some errors if the author intended to print the original ballistics of the 9.3x62, however they were standardized in 1923, if my source was correct, but the rest seemed spot-on. I have seen the diagram of the ctg. in Wikipedia noting the shoulder dimension as being .451" as well as in this article.
I have measured the shoulders on 3 commercial chambers, one from the 1920's, a sporter Mauser, a more modern Styer and a Zastava. The Zastava was the smallest, at .4525" while the Styer and my Mauser are identical at .454", the same as Ackley's IMP ctgs. on the standard case. The 9.3x62 has slightly larger capacity than say, the .35 Whelen due to the shoulder position and a couple thou larger base diameter. My Mauser base diameter is .475", while the Zastava base dia. is .474". That could explain the larger capacity I measure from my brass, being 78gr. capacity.
These are the specs from the article.
As you can see, the dimensions are quite low, compared to what actual factory cases that I measured that came out of commercial chambers.

9.3x62	Imperial	Metric
A	.471	11.95
B	.470	11.94
C	17 deg
D	.451	11.46
E	.390	9.9
F	2.039	51.8
G	.402	10.21
H	2.441	62
Max Case	2.441	62
Trim length	2.439	61.7

Daryl; Interesting differences, prompting me to check SAAMI.

https://saami.org/wp-content/uploads/2026/10/SAAMI-Z299.4-CFR-2025-Centerfire-Rifle-Approved-2-10-2025-2026-10-21.pdf

The 9.3x62 is on page 69 of 400, mostly reproduced below (yellow highlight is direct from SAAMI). Note the tolerance for the cartridge is "unless otherwise noted body dia. -0.20 (.008)" and for the chamber, "unless otherwise noted all dia +0.05 (.002), length tol. +0.38 (.015)"

Different charts, different measurements and again, compared to actual brass fired in actual commercial chambers. IF the chambers had been cut with reamers from private reamer makers as in custom or wildcat chambers, these differences would be excusable.
That all three of the dimensions I posted are from factory chambers. well, the differences are quite gross.
Unlike the CIP Euro "rules", SAAMI are simply general suggestions, while CIP are laws in my understanding.

The ideal load for me will probably be the 250 TTSX at ~2520 FPS.
Per paper, it should have nearly the same trajectory and windage as my 20" 416 Ruger's 350 TTSX load.
I think, I will start off with RL 17. But also have on hand Varget, RL-15, 2000-MR.

Once that load is settled on, I may give the lighter CEB Raptors ago.

My first dealings with loading for the 9.3x62. Dies are ordered.
I ordered Norma brass from Raven Rocks Precision. Which I will add, they were very quick getting it shipped. It is up to the USPS now. Sometimes, that is way less than quick getting here.

you will find the CEB's kill like crazy, the 210 ESP Raptor (special order only now) accounted for 13 animals up to 265 yards all one shot kills. I am now going to shoot the 200 CEB Raptor in my Sauer 100 and will start working up a load with the 250 gr./260 gr with the tip installed in my Rem 700 because I can load them longer and expect to get 2500 to 2600 fps. Have to wait on the bolt to come back from LRI having an M16 extractor, dual ejectors and the bolt jeweled. Hopefully the weather will hold and wind lays down.

Just picked up a late 1936 Oberndorf Mauser double sqaure bridge type b,with factory claws and Zeiss. Also has the extra side safety in 9.3x62..here's a few pics
