Brick and cinderblock walls.

[jsalcedo]

I went out shooting at my dads property on fathers day.

He had his new stainless ruger blackhawk .357 and I had
Spas 12 and a 629 as well as a colt 1903 .380auto

We had some extra bricks and cinder blocks and set them up down range.


.38 specials and .380 would leave a mark on a brick and crack a cinder block.

.357 110 grain JHP would knock pieces off a brick and blow holes in the blocks.

.44 mag 240 grain keith at about 1350 would disintigrate a fresh brick into about 30 pieces and turn a block into 3 shattered pieces.

12 gauge 1 oz slug obliterated all of them into dust.


Made me think about how much protection outside walls really provide.

Are a bunch of bricks mortared together stronger?

Should I think about using a smaller caliber like .380 or .38 special
for home defense?

would be fun to try with filled cinder blocks ...

Blocks or bricks, mortared into a solid wall, tend to have more structural intregrity. 12 gauge slug will penetrate if hit more than once or twice in the same area. So will 30.06 AP and similar rounds (I have seen a BAR with 20 rounds of AP do well). I don't think there are many pistol cartrides will penetrate, except some of the higher calibers, like .454 Linebaugh, probably .500 S&W, but that's a guess on my part.

Try it with an AK47.

Hi. That is extremely interesting. I did a firepower demo years ago, while in the Queen's Service, on the difference between cover and concealment. Had a couple of cinder blocks 100 yards away. Using a .308 and a .303 rifle. The .303 broke the block and penetrated but did not destroy the block. The I hit it with a .308. Ahem, there was a big high colume of dust with the first shot. I then proceeded to shoot it to pieces. What range did you shoot at? Range is terribly important for penetration. And the ammo. Hunting ammo is not the same as military ball. Still, as an experiment it's interesting.
Shot up a bunch of 48 oz tomato juice cans at one time. From about 20 yards away. Two of us used a .45acp, .223SP, .30-06SP and a 12 ga slug. Demo for teenage kids. Of all that and the only really slick end result was with the .223 and the slug. The .223 busted the can open with exciting results. The slug blew the lid of the can up at least 50 yards and back over the berm of a military range. I only saw the lid flying up and back.
