I don't think the speed is conducive to energy transfer within the beast. Sure it'll leave a big old hole in there and out the other side, but you're depending on blood loss from a small primary wound channel and not hydrostatic shock and a much larger associated secondary (temporary) wound channel and associated pressures impacting the nearby organs and nervous system.
If you get these things, even down to 300gn, hooking up around the 2000fps mark on target you'll be having much more impressive results. I'm aiming for something similar myself.

Avoid the Lee 457 diameter moulds unless you want to do work to them to enlarge, you can do it but its fiddly. You need something in the 458 to 460 range to work with most rifles, especially if you've got a deep-rifled Ballard type barrel.
Look at Cast Bullet Engineering. They do the lot - everything from 130gn flying discs through 500gn hollowpoint and 730gn toddler crayons. The positive reports I've heard are around their 400 or 405gn offerings with the large meplat for good expansion and deep penetration.

That will change if I get to the cape in 2 weeks

I have smacked a few with a hammer and they are fairly hard so expansion wont be great but given the diameter of the 45 put in the right place would be plent big enough.

If you cast then go Alox lube and wheel weights and push em as hard as you can.
Minute of pig is all you need.
If you buy then chances are powder coated is available. Look at

Doubt you buy anything other than 405grain solids though.
If you have 2206H Then just use that
