300 Blackout AR2207 or AR2206H - 110gr VMAX

[Rebhkz]

Hi all,

Has anyone out there had any success with AR2207 and the Hornady 110gr VMax’s?

I’m looking to reload my spent factory Hornady brass but am confused between AR2207 and AR2206H.

Factory VMAX loads are giving me 2432 fps out of a 16” barrel and I’m looking to try to replicate that as close as possible. With no chance of finding 2205, the above seem like the next choices.

Hoping someone has given this a go and can help out!

Thanks in advance

QuickLOAD indicates that 21.2gn (100% capacity) of 2207 will get you pretty close - 2,270fps
Nothing from 2206H will get you anywhere near - 22.7gn (100% capacity) - 1,890fps

Oh wow, so even at max load I would be losing close to 200 fps with 2207.

I feel like thats quite a big drop for such a slow round. Maybe I need to stick to factory until we get 2205 again (wishful thinking)… It would be quite a big saving reloading though.

If you could get it, have you contemplated anything else, such as H4227/H110, W296?

Buy a 308.

Hornady Black V-Max 16" barrel ballistics chart indicates Muz Vel of 2375fps.
Here's some additional powders from the Hornadys reload manual based on a 16”, 1 in 7.5” Twist rate. 2400fps is a stretch.

Unfortunately not available here in Australia. We are shafted when it comes to powders.

Im getting over 2400 fps. 2432 average over 18 rounds, measured with a Garmin C1 Pro. Fricken accurate too.

Theres this similar thread also viewtopic.php?f=3&t=18853

AR2219 - H322 might be a more suited powder...

You've got some wriggle room on your C.O.L If you stretch the V-Max out to 2.250" (2.260" hard limit) you'll get more case volume = higher muzzle velocity with the same pressure. Others may have a better opinion on this.

I saw that thread, but haven’t seen anyone with the lighter 110gr projectiles.

You may be onto something there. Hadn’t even considered 2219. Given it’s for 5.56, it could be the one to go for. As long as it still fits in a P-mag.

EDIT:
Actually after some research it seems like 2207 may still be better suited than 2219.

I covered the VMax 110g in 300 Blackout on my Youtube channel a few years ago in several parts. Back then I used to edit less and ramble more and I haven't watched these videos for a few years, but I know by the very end I was over 2400 FPS. I know another load I did with Nosler 110g I was over 2500 FPS with no pressure signs.

The best thing is to use any powder equal to H110/W296. The other thing I would recommend is a magnum primer. I use CCI #41 for all 300 Blackout and it's very similar to a magnum small rifle primer. The magnum primer is worth about .5g of powder.

I think so too, i just don't think you'll acheive the 2400fps though.

Watched most of your videos on this yesterday Wano, great info in these.
I think OP is stuck with AR2207 on this. AR2205 is the equivelant to H110/W296 but everything in this class is unavailable? Not a lot of data around for other similar powders for 300AAC for 2400fps it seems.

Yes, unfortunately, it is ADI powders or nothing here in Australia. AR2205 is like hens teeth despite rumours that it was going to come back again years ago.

Some awesome info there. But unfortunately, no equivalent powders here.
We’re also limited with primers too. We don’t have #41 but we do have #450. Not sure how different they will be.

Thank you.

The thing with my Youtube reloading projects is I come up with an idea and then people get to see what I go through to get to the final result and the lessons I learn along the way. Sometimes some projects end up easy and straightforward and sometimes not! I am expanding my 300 Blackout testing regime as I have a short barrel upper coming and eventually will add a bolt action 300 blackout.

Turns out AR 2207 is exactly the same as Hodgdon 4198, supposedly, and researching that it seems people had a lot of mixed results and if anything it seems more suited to subsonic 300 BO.

Shocking that there is not any magnum pistol powder of any type available in Australia at all, crazy.

#450 is the same primer as a #41. The 41 is "Mil Spec" for the military with a thicker cup to prevent AR-15/M-16 slamfires from the floating firing pin.

If you have not already about all you can do is try the #450 and see.

That sounds scary haha!

I think for now, I may stick to factory and just keep hoping we get AR2205 back. I don’t want to buy a whole new set of dies etc if I can’t replicate factory performance.
