Do yourself a favor. Get some Barnes bullets. They open up perfectly on flesh and make awesome blood trails. They are made of copper not lead and stay together. Everyone says they are expensive but they are no more expensive then Powerbelts. I have shot Powerbelts and Shockwaves in the past and they are not as good a a Barnes bullet. Nosler partition bullets are also very good. Powerbelts are accurate, easy to push down the barrel, and are easy to find.Thats why people buy them. If you want a passthru go with the 300 grain bullet. 100 grains of powder should be enough as well. Some of the Knight bullets are actually Barnes bullets packaged by Knight but I prefer the Barnes TEZ which Knight doesn't have.
