Bullet Penetration Chart

[denton]

A few years ago, Handloader published the results of an experiment done on 180 grain 30-06 bullets. The question to be answered was how well different brands of bullets hold up when fired at wet phone books at various speeds. I have taken just some of the data out of the chart, and made it into a graph. Each point is the mean penetration of three bullets. Vertical scale is penetration in inches. Horizontal scale is impact speed in feet per second.
