I can say for a fact that about half of what was written is bull! The "table turned over" is partially false due to the lack of info about the table. Here's what I've done by accident. 1.5" hardwood benchtop vs 44mag 240gr jhp..............winner was the benchtop! 44mag vs car doors (yes, plural).....240gr jhp went thru both doors (Subaru). FMJ's (common 9mm, 45acp and m193) ammo WILL give penetrate and possible pass thru (depending on thickness and material used). Sheetrock could change direction depending on velocity and energy of the bullet (like how bc's can help or hinder long range shots). As far as exiting thru brick with most common used cartridges...........NO. Even rocks will pass thru glass with a lot less energy. 1 thing does hold true, hp's are going to be the better choice. Can't wait for the perfect shot or situation for the ammo you selected.
