.577 Tyrannosaur.
The .357 Sig reigns supreme on these barrier penetration tests followed by the 9mm as a close second. I wish it was more popular.
Thoughts... With the. 40 S&W and the .45 ACP, you get no extra performance with the added recoil you get from those 2 rounds.
With the .357 SIG, you get more penetration at a cost of added flash, recoil, concussion, and monetary cost.
There are 9mm +P+ rounds that almost approach the .357 SIG's velocity from Underwood and Buffalo Bore if one wanted to go that route.
