I have a problem...

Urgently looking for the following ammo: Federal 9,3x74R with 286 grs Swift A-Frame and 286 grs Woodleigh Hydro Solid.
I'm living in both South Africa and Germany. In Germany I'm unable to find what I'm looking for but in South Africa I traced 2 boxes of Federal 9,3x74R 286 grs Swift A-Frame. Not many cartridges but better than nothing.

BUT nowhere I can get ammo loaded with Woodleigh 286 grs Hydro Solid! I would like to know how Federal loads its Swift A-Frame ammunition: i e powder, primer etc. then I could copy the cartridge. Woodleigh Hydro Solid I could obtain of course.I'm a reloader but my equipment isn't with me at the moment. I have moved and won't get the stuff soon. A commercial reloader will load the cartridges, I would like to make it for him as easy as possible.

Any ideas/recommendations?

None of the factories list their loads. They all use canister powders blended for them and not off the shelf powders

It's not so simple. Here's what I'd do. I would first shoot some factory loads over a chronograph to determine the velocity they produce in your rifle. Then take apart one of the loaded cartridges and weigh the powder. Then compare to published loads and perhaps also quick load to come up with a likely canister powder that is predicted to generate the matching velocity for that weight of powder and your chosen bullet. ( keep in mind barrel length) Make a few test loads, Working up to that weight powder, shooting each incremental load over a chronograph, while checking for over pressure. Determine if the powder you are testing is a close match or not. If it is, once desired velocity is reached, shoot a few groups to test for accuracy and velocity (and regulation if you are shooting a double). Good luck.
