Lucky Ammo had a good test comparing different ammos, and now they updated the list with a few more ammunitions in .380, 9mm, .40 S&W, and .45 ACP
While the list is probably the most exptensive for general viewing, there has been some criticism due to a few things, which are addressed in the new video that came with the update. Two most critical point would be the type of gellatin used, and use of shorter barrel pistols. Lucky Gunner acknowledges some possible shortcomings for their testing parameters, so keep that in mind when you go through the test.
