Has anyone had any success loading 44 magnum (18 inch rifle) with 2207, seems ADI just isn’t producing 2205 any more.
I am only considering 2207 as it is the next faster powder in the ADI range. Or is there a better suggestion, I feel like as soon as I start working on loads with 2207, 2205 will become available once again. 
What projectile you looking to use as that’ll have a direct correlation on powder choice.
Cheers Brett.
Plan on loading 240grn, figured it’s a good “middle of the road” projectile. I’ve bought a few boxes of Hornady XTP’s.
2207 is actually the next slowest powder and from what I’ve been looking at a fraction too slow for the 240gr XTP. I couldn’t find any cross reference data for anything slower then 2205 and I won’t speculate on where to start with 2207.
Next slower, you’re right.
I see 2207 is listed for larger straightwall cartridges like 45/70 and 444. Would be nice to get a confirmation that 2205 is going to be produced again. Info I have received is it has “failed”,whatever that means.
Where did you get the info from? As far as I know ADI haven’t publicly said anything since December last year.
ADI blogged in a very ambiguous way, that it may (and inherently may not) be produced in 2022. Well, we are in 2022 and it ain’t here yet.
It’s really annoying how there’s just no accountability at all over this whole mess.
You should write them a sternly worded letter, handwritten using quill of course.
I believe other people have, and have basically gotten some variation of “Le Shrug” or “Nothing we can do” from what I gather.
Obviously they were not using a good quality quill than.

Okay, as someone who has spent a lot of time working on loads that aren’t in the playbook it isn’t impossible to find a load that works with a supposedly incompatible powder. I have a .44 mag, I’ll have bit of a look into it but it won’t happen for a while since I’m already behind on other shit I’m supposed to be doing.
Haha me too! Too far behind on .357 magnum load developments. I really want to swage more 357 GC bullets too…
How many grains per mortar?
Asking for a friend.
NFI but if a box happens to fall of the back of a truck i reckon we are in business!
I am also facing the same issue now, out of 2205… Have a bulk container of 2207 man and few different 240gr projectiles… Did you manage to work up a good load?
I have been running 2207 in the 44mag under a Tigershark 240gn for the last couple of years in a Marlin 1894.
I came across some old load data from IMR that had rifle powder loads and experimented from there. There is however unburnt and partial burnt powder left over after firing. A heavy crimp and magnum primers seem to lessen this to an extent.
The powder is at the projectile base or slightly compressed. Accuracy is ok for what I want to do with open sights.
