The thingI like about the Barnes Expander bullets is they work well over a very wide range of velocities. They will expand down to 1100 fps and will do the same at high velocity and not fragment. Here is a picture ofa bullet I shot a doe with at 100 yards. 100 grain 777 pellets, 250 grain Barnes TEZ. The mushroom is textbook. Blood trail was super easy to follow. Wound channel was enormous.
