Retained weight: 32.8 gr
Max expansion: 0.543"
Min expansion: 0.312"
Neck length: 0.7"
TSC: 3" x 7"
16" barrel results:
Impact velocity: 2,775 fps

On the water jug portion, the bullet passed completely through two jugs and dented the far wall on the third jug for a total penetration of 18" of water. The first jug was literally split in two separate pieces, which were both thrown well away from the table. The bullet left a lot of fragments throughout the remaining jugs.
