I shot one deer on Kodiak with the Speer bullet, and it performed fine at the 25 yard range I shot. I recovered the bullet behind the diaphram after a quartering angle shot through the lungs; it showed great expansion, but MV was just 1150 fps in my short-barreled BH. 1400 fps and short ranges may be too high for the bullet to hold together unless the lungs are the only target. Frankly, I usually try to choose a bullet which will expand some in the lungs yet still penetrate well on quartering shots....unless you want to pass up all quartering shots. :?
