Nosler still makes the 165gr Ballistic tip. The Ballistic Tips got a reputation for being too soft and over expanding in larger game such as elk etc. About 10-12 years ago Nosler addressed the problem by making the copper jacket a little thicker. If your bullets are older than about 10 years they may not be a good option for game larger than deer. The product number may have changed with the tougher jacket, but load data is the same. If the box says simply "Ballistic Tip" they are the older design. If it says "Ballistic Tip Hunting" it is the newer, tougher bullet.

All of the powder manufacturers and most bullet makers list data online, just google it.
It would help knowing which powders you have access to. I load for 308 and could offer advice as would most everyone here. It is possible to use the same powder, but you will get poor performance from at least 1 or 2 of the 3. It is best to use powder optimal for each. The good news is that 308 is the easiest round I've ever loaded for. I've used 6-8 different powders and never found a bad load. No bad advice so far on powder choice, but there are others that work well too. It depends on which is available
When looking at load data you may find data for Hornady bullets when you have Nosler, Sierria,Berger, or some other brand of bullets. Most of the time the load data will be pretty close to the same as long as bullet weight is the same. At least as long as you are shooting lower or mid level loads. Once you start approaching max loads you may find one brand of bullet is overloaded while another is still safe to use.
The biggest exception is with any of the solid copper bullets. Load data, even with the same bullet weight is far different.
The bigger problem is brass. Pay attention to the brand of brass recommended in the load data. In my experience Hornady, Winchester, Remington and Nosler brass are close enough to not matter. But Federal brass and military surplus will give you more speed with the same amount of powder. Which means that loads in that brass may well be over pressure before you reach the max weight of the powder charge. And be perfectly safe in other brands of brass.
Primers can matter, but to a much smaller extent. If the load data specifies CCI primers and you have another brand it is safe to substitute. But you'll sometimes get a little slower or faster bullet speed with another brand.
