One of my favorite medias for shooting at with the Lehigh bullets is a gallon bag of water in front of a good sized piece of cardboard. The petals go through the bag and leave holes around the base hole in the cardboard.

I will likely be using the 250gr Bloodline this year if i can get them to cooperate in the ULA. If not ive got some older Lehigh 275gr 458s to try in the 52 or maybe the 54.
