Re: Bullet trap for home gun range

Quote:
Bullet traps are designed for specific calibers. The minimum thickness that should be considered for the steel plate if planning to only shoot .22 caliber rimfire ammunition would be three-eights inch. If you plan to shoot centerfire ammunition, at least one-inch thickness is recommended
Sorry, but I think whoever wrote this is an idiot or an engineer. (I know you're wondering what the difference is. Primarily, they are differentiated by the presence or absence of student loans. That and most idiots have non-pneumatic girlfriends.)

No rimfire is going to so much as dent even 3/16 steel. And requirements for centerfire rifles versus handguns are nothing alike. And, as others have already pointed out, the grade of steel will make a big difference.
