More .22 LR penetration:

If you'd really like, I can head out to the woods and put some holes in things for demo purposes. I don't own a .357, but a +p 9mm round should suffice as a decent stand in even if it is a bit slower if I can't borrow a .357.
Jan 22, 2016 For example the Flintlock Pistol matches up nicely with the Light Crossbow, each doing 1d8 piercing damage, but the gun can be held in one hand and the crossbow has a longer range. I wanted to have guns be able to do something special without being magical, so I added in my own version of Pathfinder’s scatter and 5E’s burst attack. Sep 21, 2010 So, being away from my books, and having a ridiculously bad memory, I can't for the life of me remember if, and if so where, there are any official rules for guns in dnd 3.5e. Specifically, flintlock pistols and muskets, clockwork guns, and percussion cap guns. Anyone know where I can find such rules? Thanks in advance.:smallsmile. Your class grants proficiency in certain weapons, reflecting both the class’s focus and the tools you are most likely to use. Whether you favor a longsword or a longbow, your weapon and your ability to wield it effectively can mean the difference between life and death while adventuring.
1) work on your math2) I've done some destructive testing. My friends during college included a bunch of gun nuts
I've shot a .357 using round nosed police-standard lead ball (non-jacketed) at a steel plate of 18 gage - which is 25.4/18= 1.41 mm thick - and it didn't go through. I've seen .357 stopped by car doors, too... on older cars, where it was as thick as 18ga. In both cases, visible deformation, no penetration.
Factors that influence penetration include incidence angle (anything other than 90° increase both the skip chance and the effective thickness), specific metal composition, specific tempering, method of working (hammer-worked is different from rolled), amount of air traveled through (drag reduces bullet energy), bullet composition (straight lead penetrates less than FMJ), bullet shape, temperature of the metals, age and flexion history of the plate.
Your 9mm probably will penetrate 1mm steel if shot within 5 yards and aimed dead on... because autopistol rounds are ususally jacketed. It also won't do much past it.
And a breastplate is seldom worn without quilt underneath. Yeah, it is gonna hurt. No, it's not going through. But the same is true of a sword.
Ignoring armor isn't the solution, especially since most firearm to body armor shots are going to be other than 90°.
