Txhunter58, This is the skinny on powerbelts. I've shot both the aero and hp, and I recommend the aero. The reason is that the hp is only good to approx. 100 yrds. The aero is good for close range , and beyond 100 yards. I have found that the bullet will penetrate the game in one side, and usually lodges inside the animal on the other. I have shot powerbelts exclusively with my muzzleloder, and all of the bullets have mushroomed perfectly. The aero tips are made for 100 yrds and beyond, they fly more stable. Well, good luck on your hunt, Turkeyhunter1......
