I like the controlled expansion bullets for most rifles that are used for big game. Partitions have a proven record for harvesting game all over the world . You can't go wrong with them. I have had great sucess with the Barnes X bullet and the Failsafe also.
When buying a bullet there is two schools. Some people like a big mushroom and rapid expansion. On deer size game these can be devistation under the right conditions. Some times with shoulder shots or angle body shots this tyoe of bullet dosn't perform as well as a controlled expansion. The bigger mushroom restricts peneration but does increase would channel size. This is a Nosler ballistic tip, Hornady SST, inter lock, Core Lokt, etc.
The second school is to get the most peneration possible. That is Nosler's Partition, X bullet, Failsafe, Swift A frame, etc. This stouter construction will give deeper peneration and it will hold together under circumstances where standard bullets will fail. Going through shoulder bone, cross body shots, the texas heart shot, etc. This is where the controlled expansion will shine. They penerate up to tiwce as much. With this style you will almost always get an exit hold
With a deer you can use either type depending on your perference. I like to be able to shoot any animal anywhere so that is why controlled is for me.
If youy are handloading try a few different one. You can set up a box of wet newsprint and can shoot different bullet and see what happens.
Good Luck
