I think you'd be better served with a cast slug with a wide meplat at those velocities.
I mostly use jacketed bullets for big game (elk and deer) in my revolvers but tend to agree with s4s4u here. The reason I say this is that the jacketed bullets you mention have to be run "up to speed" to work correctly as far as expansion goes. The cast slugs don't.
The loads you mention may not get the needed velocity to work correctly.
If you use the search engine feature here you will find a "TON" of loads for the .45 Colt.
Others with more experience with the .45 Colt will likely chime in here. I use a .454 Casull and .475 Linebaugh, and I run them fairly fast.
JMHO.
