Well, even if it DIDN'T open well, a .45 caliber hole through and through aint nothing to sneeze at which is pretty obvious from the results Chet's daughter got. As I stated previously, I've never had a failure to recover any animal I've hit over many years of using them. I like to experiment and try new bullets and such, but if I find myself on a hunt to where I want absolute confidence in my bullet, I wouldn't be afraid to use the old fallback PT Gold. Or my new kinda favorite Bloodline or Lehigh.
