+1 on trying out different loads. Your rifle barrel will have one load it likes best. Deer dont need 180 grains of killing. A 150 or 165 will do fine. It is my experience that I get a lot of meat damage with 150gr loads...They kill excellently, they just tear up a lot of meat, so shot placement is very important. I have the best luck with 165 gr loads. I usually recover the 165's especially if it is over 200 yard shot.
I reload my shells with 165 gr Hornady BTSP's. They are just as accurate, perform just as well, and are half or less of the price of the elite brands. One thing you might check is the twist rate of your barrel, and then compare to the length of the bullets you consider. My Remington has 10" twist. That twist prefers a longer bullet. I get OK accuracy from a 150 grain, but I get excellent accuracy from a 165. Your barrel will have a preference of what it likes. I load 59 gr of 4350 powder for a bit over 2900 fps. My bullet travels at high rpm and if I do my part will do MOA at 300.
There are lots of things to consider. Copper weighs less than lead. So if you go with a Barnes all copper bullet, and you want 165 grains, it is going to be longer than a 165 grain lead bullet. It will love a fast twist. If you have a slower twist, lets say 12" twist, then you might want to look at a lead bullet which will be shorter and love the slower twist. Lots of things to think about, aint there?
