I love shooting suppressed guns and after owning several 300 Blackout guns the 9×39 Russian has caught my eye as the ammo is finally available in the US from Wolf and Tula. I recently build a bolt action pistol with a remington 700 action, 9″ barrel from KAK industries, Pork Sword pistol chassis from Black Collar Arms, and MDT 6mm br magazine. I just getting into casting and found a used NOE mould on Ebay .368 280gr FN. Im interested in a 4 or 5 cavity mould in .368 in the 285-300 grain range (or even heavier) with a SP type point without lube grooves designed for HTC or powder coat…similar in shape to the HTC459-500-SP mould. Ar15 uppers have been out for a while, Krebs Kustoms is making AK pistols in 9×39, and KAK industries has Redding dies which I purchased and people are starting to reload/load this ammo from 7.62×39 cases. I have loaded some of the commercially available 9.3mm bullets with 7.62×39 brass necked up and fireformed (attached pics shows wolf round, handload before fireforming with a Nosler 270gr bullet, and a handload with a Missouri bullet co. 275 gr flat tip bullet). Anyways, maybe some people will be interested and we can get a mould made.

Have you looked at replies #5, #6, & especially #7 of this particular topic string.
A 400 grain cast bullet would by nature have to be a very blunt nose design to keep from filling the entire cartridge case with the bullet to make the 2.2″ COAL that you are looking for…Ballistically I tend to believe that it would have to be almost closer to a round nose or a wadcutter design to make a 400 grain cast weight & still leave any appreciable room within the cartridge case for a powder charge… of any sort to propel that heavy a cast bullet in that cartridge case…
Reply #7 shows the original 285 grain cast bullet design that protrudes into the cartridge case almost .600 of an inch… (.577 to be a bit more exact.) that I drew up a while back and sent to the forum for posting…
Your call on the 400 grain design thought…Attached is a 368 diameter 400 grain design concept dwg setup for powder coat.
The 400 gr cast bullet @ ~ 1.530 inches is basically a bit longer than the cartridge case itself which according to SAAMI is 1.523 in length.
One had to seat the bullet quite deep (approximately .849 deep) to get a 400 gr WW cast bullet weight to meet the COAL spec on the cartridge.
You can see how far that it takes up a good portion of the 9.3mm Russian cartridge case… when the 400 gr cast bullet is superimposed over the SAAMI 9.3 MM Russian cartridge case dimensions.
It may be that in order to get any appreciable velocity out of the 9.3 mm design that one might want to limit the cast bullet weight to around 350 grains to maintain any real sort of ballistic shape…
You now have at least the design concept image with a 400 grain cast bullet to look at.Thanks Mike,
This helps a bunch as I had no idea how long a 400gr projectile would be.
I believe that a lot of those into this caliber like myself are looking for a 300 blackout alternative that would be much more viable to hunt with subsonic. If nobody else is interested in something like this I’ll show myself the door.I’ve run that bullet through GRT and it appears that it may be onto something provided that it could be loaded to 2.2″.
Data using 8″ barrel.If you read the article in one of the recent Firearms News on firearms ownership in Russia…
One will note that in Russia apparently one needs to first apply to have a Shotgun permit & be free of any issues with said shotgun permit for at least a period of five years before one can apply for a rifled firearm permit.
The Russians apparently allow for a smoothbore version in the rifle caliber in question, & classify it as a smoothbore firearm… as there is no rifling in the barrel of that firearm.
The rifle in Russian is for all intense and purposes is a smoothbore barrel.
The article went on to say that if one does not want to wait for 5 years you can apply and get a smoothbore version permit for that smoothbore rifle version right away… without having to wait for 5 years for the rifled version.
It is also why most probably the note regarding the ammo coming out of Russia that does not hold the bullet diameters very tightly, as with a smoothbore for the general Russian public there is no rifling for the bullet to engage.
So there is really no point in holding bullet diameters very tightly on the Russian ammunition.You are correct… however you did not basically explain why that I could read from your comment.
Or if you feel that you did, then I & possibly others who may not be so informed… may possibly have missed that distinction.
That is why I elaborated on your comment; to clarify the comment details on the subject.I tend to believe that the Firearms News article elaboration… tends to more fully explain the why.
No reflection or put down was ment towards you… or on your initial comment…Just clarification… of the reasons that the cartridge basically has such loose diameter bore tolerances in Russia.
An unrifled barrel, which for all intense and purposes is a smooth bore musket barrel whether it be smokeless, or not is inherently not as accurate as a rifled barrel.However if all one cares… is that it goes bang when one wants it to… then please be my guest.
Again that last comment is not aimed at you or anyone else who is looking to try to produce an accurate round for their rifle cartridge of choice.It simply is a nice to know bit of intel, & why.
Also knowing that bit of intel may not lead someone who is not so informed down the proverbial garden path towards what might be perceived by some as a perceived ammunition oasis in an ammunition drought to stock up.Therefore if one is developing said rifle cartridge outside of Russia, & tends to want it to shoot accurately…
I would not tend to believe that utilizing the loaded ammunition from said country in regard to our combined comments will be accurate whether it is steel case & berdan primed, or brass & boxer primed.I tend to believe that many who come to the forum, who may be not so well informed… are looking for answers… and should thus be given the whole story.
Or a series of stories that tend to explain the whole picture & why.That is so that they can judge for themselves and make an informed choice…
