How hard is it to understand BROADSIDE? I have shot and killed enough deer to know what is going on. That is why I use the x. Bullet performance is NEVER an issue. The shot on that deer was as textbook as they get. The bst just dont do worth a crap at high velocities. Have even seen proof of that with 150grain in my 300wsm. If you want to take a chance, use em. I will stick with the x bullet.
