Which powder in factory load ADI 55gr Sierra Blitzking?

[FTL]

Pulled factory round and 24.36g of powder which looks like BM2. Tallies with the 23-24gn BM2 I'm using for the 55gr SBT Sierra Gameking(#1365)

Does anyone know for sure which powder ADI use for this factory round?

The powder is an "in house" blend not available to the public but is ve4ry close to BM1, AR2219,BM2. AR2219 was the closest powder to ADI use having been initially formulated for 5.56x45.

I found 2219 to be way too fast in a 223 with a 55 grain pill with a lot of airspace and down on velocity with a fair amount of pressure found benchmark 2 and 8208 just about perfect

2206H is very good, I get velocities up there with the best of the speeds I hear 223's can achieve. We use 3 here, and all are 20" barrels, not 22 or 24.
So I'm not going to go on any powder treasure hunt, especially too because it's my accuracy powder in 308 too. And fast.

I do hear about these "special blends" for factory ammo. I don't believe it in Australia at all. That's not a shot at anyone, so nothing personal. The market here is too small IMHO and Aussies dont usuallyf**k about if they dont have to.
Yeah I know about Defence production, but remember the stories about the original 2206 being used in the 144gn 7.62 ammo? It was available for us too.

A bloke local has a 223 autoloader for PP, and his pet load is 24gn 2206H with Superroos, Vmaxs and Blitzkings. Another reason why I wonder the point of "special blends". But stranger things eh?

If the powder looks like BM2 and diameter and length of kernels measure the same as BM2 then the powder is BM2 BUT it is not canister BM2.
For canister BM2, the stuff we buy in in a shop, the manufacturer will blend various production lots of BM2 and test in a closed bomb apparatus to ensure the blended batch provides consistent pressure and energy results conforming to published load data.
Whereas bulk powder supplied to manufacturing generally comes in a 200 liter barrel and is as it comes from production. The ammunition manufacturer will adjust the load to suit the requirements of the cartridge and the characteristics of the powder.
Always use the the powder manufacturer's loading guide.

i been using 2207 for 55grainers ,works plenty good and clean

I forgot to mention earlier, and I should've, my too easy 24/2206H load with the 55gn Blitzkings reload shoots to the same POA in our two bust-em-up Howas and 1 Sako Varmint 223's, and that's re-useing the ADI brass from the factory ammo you asked about.
That doesn't mean it's the same powder, won't be the same primer (reloads use CCI), but is identical in every aspect. It'd sure be a good one to try if you wanted complete interchangeability. In our rifles it does anyway.

They did a press release-type article admitting the factory .223 Game, and Blitz King ammo was loaded with their newer BM8208 powder.

I remember reading it, and pulled a couple.
It looked identical to my loads and only slightly less than my 24.6gr of 8208.
I couldn't really pick a winner between BM2 and BM8208, but found them more consistent then my 06h and 08 loads.

I had just started loading and only had the .223, so I tried everything in it to shoot more single raggeds and get it shooting flatter to 2 and 300m.

Thank you all for taking the time to reply and your helpful comments.

I've loaded in once fired ADI brass with CCI primer to factory (ADI Blitz) BTO with 23 23.5 24 24.5 (non compressed) and I'll chrony.

I get 3111fps with the factory ADI 55gn Blitz currently

What powder was that you're using mate?
Always interested in others results, although no two guns and no two shooters are ever the same.
I did notice though, that a few comments from gun shops about certain ADI powders is that a few are notoriously difficult to get consistent supply of. I do like to stick to stuff that's always there, over something that might be a few FPS quicker.
Always learning.

It's funny how rifles are all a bit different and like different things, but consistent ammo like that ADI .55gr .223 ammo seems to shoot well in just about all rifles.
I remember the keen range manager saying not many rifles don't like it.
He also said when ADI loaded it with Hrndy projies that it didn't shoot as well.
Just a great match, Sierra pills that are always consistent, so are ADI cases, and those finer BM powders that also meter through so well.
I never got V-Maxes shooting like 55 Game Kings, good varmint pill, but they just don't shoot near as well.
Seen Cleavers doing the bulk packs again the other week, not the old prices but $200 is better than the new norm of $300.

I closed up the groups a bit with the reloading, as well as getting flatter shooting to 2 and 300m.

Even with the big Sydney shops not getting the bad supply problems as much, I did just make it through the 8208 shortage with my spare bottle, I now keep 2 spares.
When 2209 got scarce, I got scared and grabbed a 4KG, and a spare is purchased well before I get half down.

Sorry, forgot to mention the powder; I'm using Benchmark 2.
Haven't had chance to test as yet.

[Fester]

I couldn't pick a winner when I was comparing BM2 and 8208.
I run a 24" barrel and settled on 24.6gr of BM 8208.

Shot like a lazer for about 7,000 rounds and can still shoot a decent group.
