A couple of weeks ago, there was discussion of shooting
milk jugs, and what kind of penetration you can get.

Today I went to the range with some reloads for the S&W 500.

350 grain 50 caliber Sierra JHP.
41.6 grains of H-110.
Chronographed at 1600fps average.

I lined up four plastic jugs. These were a little heavier than
milk jugs. They were actually windshield washer fluid jugs.
(filled with water)

The hollowpoint mushroomed on the first jug, and the petals
tore apart before exiting, as evidence in the following
photographs.

Three of the petals were found in the fourth jug.
Exit holes indicate the other three petals exited the sides
of the second and third jug.

The main body of the slug kept on going after the fourth
jug.

This is the exit hole from the first jug. The overall
patern measures 1.5" diameter. But it clearly shows
the main body of the slug passing through the center,
and the petals exiting around it.
