The key item is bullet weight. Muzzle and impact velocity make very little difference as long as the impact velocity is in the recommended range for the bullet. For most lead-core bullets, that range is 2,000 to 3,000 fps. Since both the .270 and the Grendel have pretty close to the same range of bullet weights that can impact within this velocity at reasonable hunting distances, their effect on game is very similar.
The main difference is the .270 has a flatter trajectory and a longer range to the threshold bullet velocity but one pays the price of enduring heavier felt recoil.
