I'll go along with Rey. 265 Swifts in .454 are THE bullet.
If you want to use your .475, might want to try 275 gr. Xs. I've done 5 deer with these. None ran. I've use 400 gr. and 325 gr. leads, 325, 400 g. XTPs and Speer Gold Dots. Deer don't offer enough resistance for the last bullets to do very well. Xs are far superior.
