I've finally got my 450 Rigby brass, bullets and dies together, all I need is some data.

I'm loading both Barnes X 500gr and Swift A-Frame 500gr bullets. These are intended for Buff and Hippo. If I ever hunt Ele there are Norma factory loads with the 500gr flat nosed solids that several members have advised are quite deadly on that species.

I have Norma and Hornandy brass, Federal Gold Medal large magnum primers and near every powder available.

I haven't been able to track down any load data for the 450 Rigby in the reloading manuals that I have, but have heard that 450 Dakota and reduced 460 Wby data can be used. So far it seems 4350 and 4831 are the go to powders.

2350-2400 is as far as I feel the need to go with these bullets in this cartridge, as accuracy and reliability are probably more important.

Any good starting points would be appreciated.

Woodleigh loading manual has several pages.
I will check this thread tomorrow and if no one has responded I will be home by then and will try to take pics.
 
Maybe PM @Assiehunter, he did some loading for his Rigby 459 a while back. Could search the threads and likely find his posts on it. Not recalling any specifics on what loads he was rolling up, just that it was a splendid looking single square bridge action with some lovely wood.

Expect I’ll be doing the same search before too long.

Gentleman, I want to say a thank you to everyone that posted the data I was looking for, or sent a pm. This is exactly what I was looking for.

This is what I enjoy the most about this forum. Knowledgeable people willing to share and help fellow hunters. I hope to be an asset to others in the same you have been for me.
Darrell

Not sure your price range. Have a 375 H&H with a muzzle brake. Nice rifle only fired a few times. Also a Mossberg 375 Ruger its been used and shows a few hunts on it.
