no good news for pistol/shotgun reloading

With regard to 22 Hornet, 2207 powder has load data available from ADI themselves and that is still available

Only thing I found is July, starting p48

Thanks for looking.
Does it mention artillery rounds using ADI Trail Boss?

It may not be hard for some to work out but it is defence related info after all.

I can't see why it would matter with artillery, anybody interested in the subject already knows what's in there. I would've just assumed they use some sort of smokeless for the primer rather than blackpowder nowadays, but it's possible they produce a propellant for that specific purpose. I think artillery shells are very basic compared to the enormous variety found in smallarms ammunition. I don't believe any artillery uses the same smokeless powders as we use in smallarms, except perhaps as part of the primer.

Would be interesting, 18kg of TB is a lot of volume, about the same as 50kg of a conventional powder, so it'd have to be a large cartridge.
If I had enough interest in the magazines that'd be worth spending a few hours trying to find. They would have digital copies so could search it for you in seconds, if they were inclined to be helpful, let us know you go with that.

Agree. And that type of info is well known in the industry. Just seems to me they wouldn't want to make it public.

A full case with a Berry's 147gn at 1.16" OAL holds a compressed 8.6gn of 2207 and it's enough to get the projectile out of the barrel with almost no recoil and no chance of cycling the slide on a 92FS. A similar recipie with 2205 makes a weak but passible load and will cycle.
Duplex loading is looking promising so I'm working up slowly replacing more of the slow powder with faster powder near the primer.
Yesterday I tested 0.4gn APS350 with 7.6gn of both 2205 and 2207, the rounds with 2205 were actually the best of the day, no cycling issues and the smallest 10 shot group, I don't have a chrono but recoil felt just a little lighter than a factory 147 round.
The duplex loaded 2207 rounds do now cycle the slide but still feel very weak and the group was fairly poor so I'll need to try that with a little more fast powder.
We can make our stocks last a little longer and reload more rounds over the next few years by swapping a small amount of fast powder for a large amount of rifle powder and it looks like some reasonable loads are possible, even in 9mm, but some fast powder is still needed, there's just no way around that.

This is interesting, are you still "duplexing"? I was thinking of doing this (uncompressed) with trailboss and AR2207 in 9mm or 357 mag...

You cannot do it without compressing it or it will just mix in the case major no no the object of the game is to put the fast burning powder in next to the primer so it ignites the slower burning powder in front of it.
