The sixteen .30" pellets in #1 (2-3/4") buck have been demonstrated to be the smallest pellet size that "reliably" penetrates 12+ inches into ballistic gelatin. #1 buck has the edge over 00 on cross-sectional area as well 1.17" vs. .77" and creates 30% more wound trauma.

#4 hardened shot has good cross-sectional area, but does not "reliably" penetrate (only 7 to 10") to depths that inflict enough damage on the target to be considered lethal, though I still wouldn't want to be on the receiving end. My guess is that you are concerned with wall penetration as well. #4 will certainly get someone's attention, but if you don't want them to get back up again use #1.

In retrospect, the #4 was purchased while living in an apartment, and I had far less overall knowledge of shot and clinical wound ballistics...[geez those rounds are old, lolol]

Now in old farmhouse [plaster walls, solid doors] with no nearby neighbors, so prolly time to change the requirements, especially regarding the availability and use of vests recently...

Hows that 00 'tactical' buck spoken of earlier compare with standard #1 shot ???
