When I experimented with the powerbelts, I couldn`t get much more than
50% retension, but this wasn`t the aerotip and it was when they first came out so
things may have changed.
Soon as I get my digital camera I will post some pics of them after the shot.
I haven`t shot any Powerbelts into deer though. I was shooting different
bullets into a cardboard box filled with wet newspaper to see what bullets
penetrated, expanded and held together the best. I`ll try some aerotips
and see what happens
