All of the old school powders, 4064-4831-4350-760, work very well in 30-06. I think your choice of 150 grain would be excellent for deer. The 180 grain works for both deer and elk. Shot two mule deer with 30-06. One was 70 yards that was a hand loaded 150 grain Remington corelokt, 1 shot. The other mule deer was 250 yards away and I was using Winchester 180 grain round nose soft point, had an elk hunt a month after deer. Luckily I had shot it out to 300 yards and knew how far it would drop. 1 shot, hit buck in spine. There are much better bullets out there nowadays to choose from. A couple years later shot a spike bull at 60-70 yards with that same 180 grain. Put the bullet in the sweet spot just behind shoulder, all it took was 1 shot. I have also killed a couple of cow elk with a 308 using the 180 Hornady Interlock Btsp. You might consider a 150 or 165 grain Accubond and just stick with one bullet. If you go all copper, I would suggest going light 150 grain Barnes TTSX for both animals. Load the copper bullets with the highest safe velocity to ensure reliable expansion. Just a few more suggestions to get you started. Good luck!
