Ohioans For Concealed Carry Discussion Forums

I recently picked up a bolt action rifle Bushmaster 450.
I am hoping to reload for this rifle, but cannot find ANY load data in any of my reloading manuals.
Anyone currently reloading Bushmaster 450 that could offer some insight as to how to get started?
Thanks!

I notice that the Hodgdon site does list several loads for this cartridge with different bullet weights and several powder options.

Thanks for the response.
I purchased the Lyman 50th addition reloading handbook.
It has what I’m looking for.
