I have used 150gr Hornady Interbonds in my .270Win for the first time on Kudu. Velocity is in the region of 2900fps. Distance to Kudu was +-120meters. Penetrated on the front broad side crassing the shoulder bone and ribcage. No exit on the other side, but kept 84% for original weight and the mushroom was 2.34 times the caliber size. Excellent!!!
