Could a bullet go through tape?
« on: 09/01/2008 00:09:02 »
A roll of supersized Crystal Clear Ducktape (the clear packaging stuff). Do you think a bullet could get threw it? Dad was like this stuff is hard and dense I doubt a bullet could make it threw. Do you think it could?

Thanks Sim

Hmmm..how big is the roll !! ??....the right bullet fired from the right gun could probably do it.....depending on the size of roll !!

There are some remarkabe new innovations in bullet and gun technology out there.

its at least an inch thick all the way around. I'd go test it in the back yard, but I don't think my parents would approve of that

Nope !!..I am sure your folks would disapprove.......except the shop that sells ducktape !!

Well..if it really is just an inch thick then there is most definitely amumnition out there that will go through it.....I have seen bullets shhot through walls.....and over a foot of solid plexiglass !....

Wow that's purdy crazy..but do you think it would with a little handd gun?

Ugh i've pulled a Karen so many time today it ain't funny lol

I doubt it !..I 'm pretty sure a little hand held gun will not do it........but then...I'm not really a ballistics expert...and being a sheep....the best I can do is use my catapult to sling rabbit poo at Daisy the moo moo in the next field !!..she hates that !!

Maybe I should go buy a roll and take it out and shoot it sometime. But I could see it. I'd shoot myself and I"m purdy sure that no one would be home haha that woudln't be good

I am no expert,but I think even a handgun which I have shot on many occassions would go through . Depending on distance and things!

I asked my brother who is an avid hunter and knows everything (that's what he tells me anyway) and he says NO.  He saw an experiment using a jellied body and the bullet didn't go all the way through.  He says the bullet mushrooms on impact and loses its energy and can't make it through, but an arrow could.

I liked my sister-in-laws answer better though.  She says YES a bullet...any bullet absolutely can go through a roll of any kind of duct tape as long as you shoot it through the hole in the middle.  ;D

Does not this rather depend on whether the bullet is soft nosed or fully jacketed?

It also depends on the caliber and on the tipe of gun. I think that tape could easily stop a .22 from a target pistol but it wouldn't be enough to stop a 0.308 from a carbine.

I'd be surprised if calibre was as important as muzzle velocity.

Yes, a high calibre bullet carries more energy (although, to be fair, the energy is proportional to the mass of the bullet, which may not necessarily be directly related to the calibre), but the wider bullet needs to create a wider hole in the target in order to penetrate, and I would have thought that would have offset any advantage in mass.

A high velocity, hardened, .22 bullet would, I would have thought, had a better chance of penetration than a .308 with a similar energy.

It depends on both, and on bullet's energy, ecc. but small calibers can't have as much energy as higher ones.

Technically, that is not true, although it is commonly true.  You are assuming a correlation between calibre and mass, but there can be other factors that effect the mass of the bullet besides its calibre (e.g. it's length, and the material it is made of).

That as an aside, you have not addressed the issue of the bigger hole a larger calibre bullet needs to make, and so consume more energy making it, than would be true of a smaller calibre bullet.

Easily addressed: to make a hole of radius r and thickness l, you have to remove all the material from a cylinder with the same dimensions; the energy needed is proportional to the external surface of that cylinder, which is proportional to r, while the bullet's mass is proportional to r2 (assuming it has a cylindrical shape too). So a greater bullet of the same shape has a mass at least r2 greater so its energy (if it has the same speed) is such greater.

Not convinced about this.

I am not denying that if you are trying to punch a neat round hole through a relatively thin sheet of metal, using a flat nosed punch, and where you can neglect the elasticity of the materials involved, and expect a nice neat round piece of metal to fall away from the hole, then your calculation is no doubt correct.

The reality is that a 1 inch thick wad of tape cannot normally be punched through in that manner.  The force needed to punch though in that manner is likely to require a weapon with a recoil and weight that would disqualify it as a hand held weapon.  Furthermore, the compressibility and elasticity of the duct tape would almost certainly make it even more difficult to consider it in that way.

Rather, I would imagine that a jacketed bullet, that is likely to be a pointed rather than flat nosed bullet, could concentrate the force at the tip, punch a small hole in the duct tape, and then compress the duct tape sideways.  I am doubtful that your simple calculation would work for that.

Bear in mind here that the limiting factor here is the amount of energy a specific type of bullet can carry (you can create bullets with almost arbitrary amounts of energy), but rather with the amount of recoil the shooter can cope with, and the barrel pressures you can sustain within a weapon of a reasonable weight.

That a hard pointed bullet will go through better than a non-hard pointed it's quite obvious; the problem is to establish what two different calibers bullets with the same characteristics will do. My idea is that a greater caliber will go through more, however I presume we should wait for someone to make the experiment.  :)

Ever the scientist, I have just conducted this experiment this afternoon. Marlin .22 mag bolt action carbine and 1 roll (of 2) clear duck tape I that came from Wal-Mart) hadn't used. I goes through both sides of the tape from 6 yards. The tape was held in place on the target board by 2 pieces of clear tape from the used roll.

I think that a .22 mag hand gun would do the same, and as well as a .22 long rifle cartridge. It went through both sides of the roll of tape and the 1/2 inch particle board it was taped to.

I DID THIS AT THE GUN RANGE, PEOPLE. Don't do it at home.

Good Job... I was fixing to snitch my sons gun and my husbands and test them on the tape myself! LOL Great job with the stats~! YAYYYYYYYYYY jim Bob.. I thought it would go through!
