Detective/Forensics Question

[Andy in Germany]

I'm working on a story, nothing serious, just to see if I have a stamina and capability to write a long story, and to be honest I'm working on the till at work and it can be pretty boring.

I'm working on a scenario involving a firearm, and one piece of information is two matching bullets, in the sense that it becomes clear the same gun was used to shoot at two different people.

Being European I've never seen, let alone handled a genuine firearm, and I'm not even sure what search terms to use so I've got a few questions.

If you have two bullets from the same gun, can you tell the calibre?

How easy is this if the bullet hits a solid object like a wall at speed?

Any use?

using what i recall from watching cop shows on the telly... I'd say yes on both counts. Forget reality. It is fiction after all.

@Andy in Germany you need to watch CSI Las Vegas or New York
According to Gil Grissom, the answer to your questions is Yes and Yes.
I have also read many crime novels

In the books I read they can usually match a fired bullet to the gun it was fired from (matching marks on the bullet with the inside of the barrel?) So I'd assume that two bullets from the same gun would have similar markings.

But I've never handled a gun either.

The I'm working on a story routine. Yes they can tell both rounds came from the same weapon. Chuck the gun in a river and hope you didn't leave your prints on the rounds.

Maybe the shooter was using ice bullets!

Hang on, I'll write that down...

 

[Drago]

Don't handle rounds bare handed. Even if you wipe them clean they can still get a lift off the brass as the grease in your fingerprint etches the surface. Google Dr John Bond for more info.

Check "Most Wanted".

Writing a story? Yeah right, whatever.

Come on fess up, you've whacked someone and you want help with destroying the evidence.

Why doesn't the good guy catch the bullet in his teeth before it hits the wall?

 

[Supersuperleeds]

Maybe the shooter was using ice bullets!

If ever my broken body rocks up as if I've went 5 rounds with Edward scissor hands, someone please show this post to the cops.

 

[classic33]

Be like me. I've two seperate sets of fingerprints.

The inked set didn't transfer over correctly. So using the current system they'd never match me.
