The 240-300g XTP will surely drop your deer with no problem. And are very accurate. However, the most over looked mistake/problem most shooters make is over-driving their favorite bullets[&:]

Even those tough SST's, with 3-pellet loads, will Splat on deer at 20-30 yard close shots. And you may know all this already, so I'm just reminding you of normal ballistics

A 80-100g of your favorite powder will take any north American big game out to 150 yards easy. So if you know your usual shooting distances, you should be able to go with a medium speed load to cover the terminal impact from 30-150 yards.
