Most bullets can be found in the various forums or youtube. Some of the testers you learn to respect their results.
Then the home boy water jug test is just an easy way to confirm that your gun does a good job with the bullet. After a while you end up with a number of bullets that you can compare the expansion and number of jugs penetrated to the testers results for the same bullets. You then have a good idea if you can use the water jug test a a guide to rounds you want to carry.
I am responsible for the rounds and carry and I own the bullet where ever it ends up. I do get a kick out of shooting water jugs. Must be the twelve year old in me
