Measured New Lapua 9.3 X 62 Brass Head diameter .471 Lapua brass Resized brass head diameter with current RCBS dies .472

Fired Lapua brass to my Pacnor chambered 9.3x62 rifle head diameter .474

Measured resized RP 06 brass head diameter .467

I will continue using my RCBS dies which I prefer to non vented Redding and Lapua 9.3 X 62 brass have had no issues

I bought my dies in 1999 and they are RCBS. I don't recall others being available then? I also bought 200 pieces of Norma brass, again, all I recall being available then in the US.

I'm glad you hit on that non vented feature. One of the dumbest moves by some of the die manufactures out there. I recently bought a Horandy die set for a new cartridge I started handloading and was very surprised it didn't have a vent hole. I took it back and got my money back and bought RCBS. I tried. This hate was stemmed from using a competition die set for a 6WOA I had for a while. I'd always get tiny dimples in the shoulders of the brass when re-sizing. Totally frustrating. Garbage as far as I'm concerned.
That's where I was at when I had my 9.3x62mm. A great combination. Loaded very good ammo, as I stated in my previous post. Ran blemished Noslers when they were a great deal and affordable to practice with:


That rifle would lay them right in there and thought it was a varmint rifle. 400 yard shots were cake walk with that rifle and load.

Jesus.
This took a turn, didn't it?!

As I said in my original post, I will be buying (actually have bought) 9.3 brass to load.

My only thought on the ought-six brass is that I have tons of it, I know that it's sub-optimal but doable & I don't need to reuse it. Cheap practice without getting excess wear on the real stuff.

Speaking of the couple of thou difference in rim diameter; I've been shooting 6.5x55 in a couple of converted '06s for years with zero problems. Same difference in rim diameter.

Hang on...I have some more random stuff to add.

Hahaha!

Well I don't think the rim diameter is the issue. the head diameter is in my mind. Going to the extra work to fireform 06 brass that has .005 to .006" less head diameter than spec. to use 1 time seems dumb to me. Build or buy a 35 Whelen or 338-06 would be a better use of the extra brass. I have had split necks with Privi and S B once fired brass, nothing wrong with my cz-550 either. But those 2 brands aren't the same quality as lapua,nosler,or Norma as a fact. You went to no small expense to aquire a 9.3 and supplies why you being a cheap Charlie now.?..mb

If you have split necks after once firing of PPU brass, there is something wrong with your rifle, dies, or your loading procedures!

When I had a 1903 Springfield rebored to 9.3x62 by JES, I grabbed a new Hornady New Dimension FL sizing die off eBay for $15 while I was searching for a full set. It has turned out to be one of the most precise and accurate dies I ever owned. I very carefully measure the effects of all my sizing dies on my brass, testing for runout. These are near perfect. The next one off the line might not have been, who knows.

That said,
The shoulder being further forward on the 9.3 than the '06 is a big deal. You can't just neck it up.

You have to neck it up further/larger and then neck it down again forming a false shoulder to prevent headspace problems.

I neck it up with a .375 expander button----works well!

Or fireform with Privi 285 gr round nose seated against the lands

I like my RCBS dies and Laupa 9.3 X 62 brass don't want any case head seperations with 06 undersized brass!

I would have expected the long, tapered throats on the standard 9.3x62 chamber to preclude that. Especially with the Privi 285 being such a short bullet.
Have you (or anyone else) successfully fireformed 30-06 to 9.3x62 by jamming the lands?

Thanks,
Rex

When I built my 9.3 I was experiencing misfires.

Contacted RCBS about the problem and, long story short, they admitted their dies for that chambering could be problematic.

Went to Redding and all issues went away. This was with necked up brass as well as factory 9.3.

I have done it this way. The throat on my 9.3 allows for a 3.200 oal. with the 286 Privi, so no long taper on mine and even with a long taper the round nose would contact the rifling.
The Privi 286 is not a short bullet

Here is a 286 Privi seated to touch the lands. As you can see it has plenty of room to seat further out.
Next to the Privi is a 286 Partition, it could also be used for fire forming, kinda wasteful though...
As for the 30- 06 brass base being smaller, it's a one time deal, your 9.3 die will not size it back down, leading to repeated stress.
This pic should remove any doubt as to whether I am making things up

There are Redding dies and then the rest.

I used the Cream of Wheat "CoW" to make my 9.3x62 cases from WW 30-06 brass.
I annealed the neck area after forming and they have worked well in my rifle with hunting loads.
The head area looked normal in my rifle and I have no concerns about using formed brass.

Thanks for the follow up and I was of course NEVER implying you were making things up. But I will say you have a most unusual chamber. It's great that you can jam the lands and thus effectively fireform necked-up 30-06 in one step.
But the OAL where the 286 Privi touches the lands in mine is 3.53". For the 286 Partition it's 3.59". This is a JES re-bore with what I understand to be a pretty standard 9.3x62 chamber. The OP wrote he was having a 30-06 "hollowed out" to 9.3x62, which implied to me a rebore, and I would expect it to be JES's. If this is the case I don't expect him to have the advantage of such an unusually short throat, thus my comment:
"I would have expected the long, tapered throats on the standard 9.3x62 chamber to preclude that. Especially with the Privi 285 being such a short bullet.

Thanks for answering back and confirming that indeed you have.
Interested in what the other 9.3x62 owner's throats allow. Are there any more as short as ibfubar's?
Sir, what brand is your rifle, and is it a factory or custom barrel?
Thanks,
Rex
