I shot powerbelt bullets with 100gr of triple 7 pellets for several years and either they dropped right there or you had to get a tracking dog. I switched to the shockwave bullet and was very happy till the last 2 deer I killed with them. I shot about 10 all with pass throughs, but due to shot angles I recovered the last 2 from deer that didn't pass through and neither of the bullets expanded. I have pics of one ill try to find. So I changed to the hornady xtp 245 gr and so far so good, great expansion and nice blood trails.
