Thread: 9.3x62 loading

Take a look at 9.3x62 journal.
Heaps of loads , and history on the cartridge.
The South African Author is actually based in Auckland now.
You can buy his book as an e book. Well worth it.

Don't know if this helps but Vihtavuori N130 is listed as an "equivalent" for AR2207/H4198 and Vihtavuori have load data for 9.3x62 and 285/286 gr projectiles using N130 here https://www.vihtavuori.com/reloading.../?cartridge=92

Greetings,
That is some interesting data. Based on that the 48 grain load of AR2207 looks a bit stout but perhaps not so much with the PPU projectile which is likely to be softer. A better longer term option might be to switch to AR2206H for which pressure tested data is available and is easily downloaded to the velocity you require. I don't know what the availability of AR2206H powder is not having bought powder for several years but it is the can that I get of the safe most often when I am loading.

funny you say that GPM as the .444 loads my old ADI manual is 4 grns less than the Hodgdon equivilent of the two powders listed above.....
that old ADI manual is the very first edition paper one..has some really weird loads EG 2206 in .270w (it worked ok but very low volume fill)

Greetings,
The old ADI/ Mulwex data is all over the place with little, if any of it having been pressure tested. There were still some of the super hot loads in their manual as late as 2000. ADI started working with Hodgdon to supply their powders around 1990 and perhaps earlier. The online ADI data still has some of the old stuff but is easy to spot. There is no pressure data and the inclusion of AR2206, AR2213 and other obsolete powders hint at its reliability. I regret the loss of AR2206 which, to me, was a better powder for the .223 than AR2206H, its replacement. Some new data has appeared for AR2206 in current ADI listings for some .223 and .308 projectiles so perhaps it is still available in bulk to target clubs shooting FTR. Handloading becomes more complex the more you learn.

Greetings @JohnDuxbury,
I have come up completely empty on data for AR2207 in the 9.3x62. The nearest I got was some data for H322, AR2219 in a wildcat 9.3 on the 350 Rem Mag case developed by John Barsness (gun writer) and Charlie Sisk (gun maker). The usable case capacity of the wildcat is about 1.5 grains less than the 9.3x62 so the loads will develop less pressure in the latter. John used 52 grains of H322 for 2,415 fps in a 23 inch barrel in his wildcat. The load was tested in a pressure trace system at less than 60,000PSI. John wrote an article in Handloader 237 about the round.
None of this helps with the question form your OP. The data offered for N130 is likely the best to be had but it is a different powder. AR2207, H4198 is a very flexible powder used a lot in reduced loads and cast bullets which is likely where your data came from.
Best of Luck and Regards Grandpamac.

I remember reading that article, as a mate of mine who was a big fan of the 350rem mag but found it hard finding good projectiles , where the 9.3 projectiles are easy to find in Europe , was considering it.

Greetings @Friwi,
My son grabbed his 350 RM headed out the door at Kiwi Saddle while I and the two others in the hut chatted. Seconds later kaboom, my son had shot a Sika hind about 50 metres from the hut so the rest of us trooped out to inspect the results. Obviously the deer was most seriously dead. What was most interesting was that most of the chest cavity contents were sprayed on the scrub and there was not much damage to the balance of the carcase. 250 grain pill at around 2,400fps if I recall. Did much the same on a big Red hind.
Regards Grandpamac.

Very keen to see what you end up with. So no go for the 2207? I use that in my 45-70 but I only use 44.55gns tops with my 350gn projectiles. I drop that to 42gns if I use a 420gn hollowpoint.

I'm interested to know if anyone has made cast subs for a 9.3x62? Been keeping my eye out for these rifles but they're rare it seems yes?

I think Robert in Tokoroa has some if he is still casting
@shooternz

I may have some 290 grain 9.3 cast I am not casting at present I am waiting for an eye operation
I can't see well enough to cast decent bullets at present, I will have a look and see what I have,

Found it!
It was from an article by Ken Kempa, a gun writer who did an article on a Sauer 101 in 9.3x62 in 2015, and also supplied a comprehensive load data sheet. He recorded loads with 286 Hornady and Partition bullets with H4198 (amongst all the other most relevant powders also.) He seems a reputable chap, and is published in one of the Barnes reloading books, and also Hawke bullets.

50 grains with the Speer 270 grain bullet for 2381fps and 48 grains with the 286's for 2190 fps.

Greetings @JohnDuxbury,
This is one of the challenges of loading for European cartridges in a European rifle using US data The European rifles often have larger groove dimensions and sometimes different diameter projectiles. Consequently these rifles will produce less pressure with the same loads as their US counterparts. Additionally a European rifle may produce considerably less velocity than shown in US handload data especially where the cartridge has been domesticated for the US market. This does make life more interesting for those that load them.

I found this to be true with a custom rifle that I had built using a Bartlein barrel. I started out loading 10% lower than published data from Euro manuals, and ran into pressure signs with some bullets at what would be considered mild loads.
Cheers

In this case it is probably more of an individual rifle thing - I have tested this load in two 9.3x62's; same bullet, same tin of AR2207 powder, both rifles Husqvarna 1600's with the same length barrels. One rifle got 2200 fps and the other 2020fps. (The chronograph I used is well tested and is quite accurate)
Interestingly, (I suppose) both rifles recorded very close to the same velocity when loaded with AR2209 loads.
