Heres a picture of a 295 grain power bullet recovered from a deer. The bullet appears to have retained most of its weight. It sure got the job done.

Yes the buck i shot last week had a similar looking pbelt hung in the skin on the opposite shoulder, and they shoot 3' groups @ 100yds if I do my part
I had the bullet but let my son hold it and now who no where it is

yeah thats the same hing that happen to my deer i shot with my muzzleloader useing powerbelts and they seem to do a great job and the deer didn't go more then 20 yards before droping to the ground
