I hunt moose
I have been shooting a 458 winchester since the early 70s and alway used cast bullets to hunt
my favourite loads is the Saeco mold 545 gr. wheel weight air cool

shot many moose and they just drop there....

decided to buy a Sako 85 Brown bear in 450 rigby
looking for loads and info on this cartridge I found this forum that I find interesting and full of info
has far has I can see I could be of help with reduced loads and full in the cast department and north american hunter.... cast are effective and permits you to shoot moore with the big bore...
will begin to shoot my 450 has soon has the snow melt
will do my best to post result.....

Welcome to our place @canuck4570 Cast bullets are certainly good killers of game and of course are excellent for practice loads not just in the big bore. I have moulds for a mine from 6.5 up to 40. Had moulds for the 404 Jeffery and 458's but sold the rifles and the moulds.

How does the case volume of the 450 Rigby compare to other more established rounds of the same caliber such as the 460 Weatherby or 500/450 3 1/4" (NE/BPE)?

These have been around long enough for a wide variety of loads to have been developed and might give you some good ideas where to start.

You could also use one of the internal ballistic programs. You'll just need to measure case volume via filling it even with the mouth with water and weighing it. Best way to do it is to weigh the case empty, fill with water than weigh again and subtract case weight.

Either method, give yourself a 5-10% starting margin and work up/down in small increments.

Happy shooting!

The 450 Rigby case capacity is about 3.5% less than the 460 Weatherby.

Throat length (freebore) is another matter to consider...
