Its gonna be hard to find as accurate ammo for a 270 Win as that loaded by hornady using their SST bullets.
I use it in mine as a target round. Works great on deer. For heavier animals such as Elk I use the 150 Inter bond. It has the same BC as the 150 SSTs but the jacket is bonded to the core, it holds together better then the SSTs on Elk size animals.
I use mostly SSTs because they are cheaper then the IBs but they have the same BC, shoot at the same zero at the same velocity as the IBs of the same weight.
