The only bullet I hunt with anymore are Barnes Triple Shocks. They mushroom to twice size almost immediately on contact, retain well over 90% weight and the hydroshock is devistating to the prey. You need to experiment with them for seating depth to find what your particular rifle likes (usually .050" - .080" off the lands) but they preform great when you find the spot. I've had Sierra GK's vaporize on contact (+2750 fps) where this problem is non-existent with the Barnes at any speed.
