Does this big bore cartridge exist?

458 Lott? easy to find bullets and brass. A real thumper, but not too crazy.

That’s probably the most logical choice but as an owner of a 458 WM we’re not allowed to like Lotts haha, I was hoping for something a bit more of a step up.

Now that I see 450 Rigby factory ammo can be had it’s becoming a serious consideration…

470 Capstick, both Aria and Hendershot’s has ammo! You can load a 600gr round over 2200ftps!

495 A square

Without the factory ammo requirement, I’d say the easiest path is the .500 A2.

The readily available factory ammo component is a big one for me. I don’t reload, like the convenience of buying it off the shelf.

.470 capstick - the cooler Lott.
