With throats that size....
...you have LOTS of good options. I would size bullets .451" (or .4515" if you have that sizer) and play around with whatever cast bullet designs interest you. I am a big fan of the Lee 230 grain TC (with the real lube groove), but there are many others that will work nicely in your gun.
