The 162gr A-Max worked very well on whitetails when fired from my 7STW. Broadside shots or high shoulder shots both proved to be rapidly fatal.
I'm assuming that you are shooting one of the 300 mags; the 208 A-Max would be more bullet than needed but (IMO) would get the job done at almost any conceivable range.
I was going to use them in my 300RUM but the Berger 210VLD was producing tighter groups in this rifle. The A-Max is usually easier to find, less costly and just as accurate. Both are reliable at dispatching deer.
