I'd say your projectile and velocity will do just fine on deer.
Personally if you want expansion, aim for bone. Line up the heart with bone either on the near side or the far side and you will have your venison.

If you have a meplat on the bullet it will do better I suspect than a round nose.

You may want to keep those for plinking and investigate another bullet for hunting. Carolina Cast Bullets may be able to help, I'd contact him and talk to Jerry.

Whatever you are willing to put up with, is exactly what you will have.

When your ship comes in. ... make sure you are willing to unload it.

PAYPAL, sucks and I will never use them again. I recommend you do the same.
